- The invention comprises a portable locator unit useful both as a cellular telephone and portable global positioning system that provides latitude and longitude information remotely to a base unit display. The system includes a small hand held receiver that receives signals from a satellite global positioning system and timing and computing circuits to provide location information signals. The hand held unit also includes a modem and transmitter to a cellular telephone network which is connected to the base unit computational system and display. The location of an individual or object can thus be determined at the remote station through the use of the cellular telephone network.
- A system and method for locating a portable locator device in a communications network. The portable locator unit (PLU) (4) is activated either by an external signal (62) generated in response to remote activation source, such as a subscriber (6, 8) or PLU detector (106, 108), or by an internal activation signal triggered e.g. by the wearer. Once activated, the PLU (4) transmits a locator signal (66). This location signal (66) is received by one or more network service nodes (20, 22, 24) which forward the information along with identifying service node information to a network location processor (26, 28). After having determined the location of the PLU (4) from the received information, the network location processor (26, 28) forwards this information to a designated source, such as the requesting subscriber or other authorized user (6, 8).
- Tamper resistant body-worn tracking device to be worn by offenders or potential victims for use in a wireless communication system receiving signals from a global positioning system (GPS).

- A radio locator system uses transceivers located in a mobile and at least two stationary stations. Each stationary station serves as one end of a surveyor's baseline. Therefore, since the transceivers are located at opposite ends of a line having a known length, their broadcast signals provide direct distance measurements of two other lines extending between the individual stationary stations and the mobile unit, thereby cooperating with the known line to complete a trilateralization. Each station in the system is identified by a uniquely encoded stream of pulse bursts, each burst encompassing a wide, preprogrammed change of frequency for eliminating interference between the signals used in the locator system and the signals of other users of the same frequency band. An inversion of the preprogrammed frequency change is used for the return of the ranging system signal in order to substantially eliminate or suppress echo returns to the mobile or interrogator station. The sound of the preprogrammed station identifying frequency changes is sometimes called “chirping”.

The system is also adapted to monitor persons in hazardous environments such as radioactivity or poisonous gases or even to monitor inanimate objects such as automobiles.
- A telecommunications system and method is disclosed for defining location services in a simplified manner based upon whether the positioning request is an interactive request or a batch mode request. In order to initiate a positioning request, a Location Application (LA) must first register with at least one Mobile Location Center (MLC), define the service parameters specific for that LA and receive a Location Application Identifier Number (LAIN). Thereafter, the LA can send either an interactive or batch mode positioning request along with the LAIN. An interactive positioning request is a request to position a specific subscriber or group of subscribers immediately, while a batch mode positioning request is a request to position a subscriber or group of subscribers when a particular event defined by the LA occurs. Advantageously, the definition of location services is decoupled from issues, such as the point of origin of the request, the identity of the subscriber to be positioned and authorization options.

CPS satellite signals can be used for timing control.
- A navigation information system includes a communications system having a fixed part and at least one mobile part, the fixed part including data storage and processing for identifying the location of a mobile unit, generating guidance information appropriate to that location and transmitting it to the mobile unit. By locating most of the complexity with the service provider, in particular the navigation computer and geographical database, the system can be readily updated and the capital cost of the in-vehicle system, which in its simplest form may be standard cellular telephone, can be minimized. The user makes a request for guidance information, and the system, having determined the user's present location, then transmits instructions to the user. The user's present location can be determined by a Satellite Positioning System.
- A system which tracks and monitors a vehicle by utilizing cellular communication componentry and global positioning system componentry is disclosed.

These operations typically also include preprocessing and post processing of the GPS signals. After a snapshot of data is taken, the receiver front end is powered down. The GPS receiver in one embodiment also includes other power management features and includes, in another embodiment the capability to correct for errors in its local oscillator which is used to sample the GPS signals.

- Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 6 illustrate the global positioning and tracking system of the present invention indicated generally by the numeral10.
- The global positioning and
tracking system 10 is illustrated in FIG. 1 and includes acentral monitoring station 12, a trackingsatellite 14, alocal relay station 16 and aportable locator unit 18. Thecentral monitoring station 12 is able to monitor movements of an activatedportable locator unit 18 upon either contacting theportable locator unit 18 or upon receipt of a signal generated by theportable locator unit 18. - The
portable locator unit 18 is a tamper resistant and detectable portable unit which is releasably attached to an item of personal property or to an individual such as achild 20 as illustrated in FIG. 1. Thechild 20 in the figure is being watched by aguardian 22. Thecentral monitoring station 12 communicates with theportable locator unit 18 via a public communications network such as POTS, cellular, PCS or the internet. The main purpose of thesystem 10 is to locate the wearer using progressively more accurate technology methods for locating aperson 20 carrying theportable locator unit 18. These technologies range from wireless Base Station ID location technology which can locate thelocator unit 18 to a position within an area of between 1-10 square miles to the Global Positioning Satellite (GPS) system using wireless Internet as the communications medium which can locate wearers of theportable locator unit 18 to within approximately 5 meters. A sonic or radio frequency beacon generated by theportable locator unit 18 facilitates a final approach to a desired person or object. - The
system 10 of the present invention includes a client-server protocol such as SMS/QNC sessions in order to provide efficient location services including a paging function. An emergency call can be placed to thecentral station 12 by a person wearing theportable locator unit 18 by pressing apanic button 42 as seen in FIG. 2. A tamper detection sensor can automatically initiate an emergency call as well upon detection of tampering with theportable locator unit 18 as will be discussed hereinafter. A nonemergency call can also be initiated by the wearer upon activation of thenon-emergency call button 44 as seen in FIG. 2. In this instant, thecentral station 12 informs a designated guardian on contact list as to the whereabouts of the user. A bread crumbing mode of operation allows for efficient and flexible tracking of thelocator unit 18 given a limited battery power. The locking and unlocking mechanism and suspending of the locator unit operation (for example, for airplane traveling) is controlled by an authorized Key fob or by thecentral station 12 via a wireless network providing maximum security and usability. The operation of the system to perform these tasks will be described hereinafter. - In the normal mode of operation, a GPS unit of the
portable locator unit 18 for communicating with theGPS satellite 14 is normally turned off and the system for communicating with thecentral station 12 is placed in a listening mode similar to that of cellular/PCS phone systems. When thecentral station 12 receives a call from a client requesting a location on a particularportable locator unit 18, thecentral station 12 initiates a communication with theportable locator unit 18. Thecentral station 12 contacts theportable locator unit 18 using a wireless communication channel via local transmission/receivingstations 16 which relay the signal to theportable locator unit 18. The signal transmitted by thecentral station 12 to the local transmission/receivingstations 16 is indicated by the arrow labeled with the numeral 24. The signal transmitted by the local transmission/receivingstations 16 to theportable locator unit 18 is indicated by the numeral 26. Through this communications channel, thecentral station 12 provides instructions on how to report the location information back to thecentral station 12. The instructions received from thecentral station 12 could include aiding information for use by the GPS unit to obtain location information more quickly. Upon receipt of the instructions from thecentral station 12, thetracking device 18 ends the communication with thecentral station 12 and turns on the GPS unit therein. The GPS unit computes location data with or without aiding information (such as time, frequency and ephemeris) from thecentral station 12. At this time theportable locator unit 18 establishes a wireless communications link with thecentral station 12 and provides the location information thereto as is indicated by the arrows labeled with thenumerals portable locator unit 18 also generates a beacon indicated by the arced lines labeled with the numeral 31. The beacon is a sonic or radio frequency signal which aids in locating the user when at close range. - An exemplary embodiment of a
portable locator unit 18 is illustrated in FIGS. 2 and 3. Theportable locator unit 18 is typically worn by the user around thewrist 32 similarly to a bracelet or watch. Theportable locator unit 18 is preferably made of an uncuttable material so that it is difficult or even impossible to remove without the proper unlocking mechanism. Thus, theportable locator unit 18 can be used without worry for tracking the location of a child, a prisoner or inmate out on a work release program or furlough, senior citizens in need of medical care, personal property or even athletes such as hikers or mountain climbers moving through dangerous areas. Theportable locator unit 18 includes anouter surface 34 having a smooth texture and adisplay 36 on aface side 38 thereof. Thedisplay 36 includes aclock 40 thereon for indicating the time of day. Thelocator unit 18 has an internal clock that is displayed. This time is set when the PCS unit in thelocator unit 18 registers with the PCS tower. The unit automatically displays the correct time in the area worn correcting for daylight savings time when required. The time is very accurate, possibly to within a second of world time, but not accurate enough for the GPS portion of the unit. Also positioned on thedisplay 36 isindicia 41 indicating whether or not theportable locator unit 18 is in a locked state about thewrist 32 of the user. Additional indicia may be displayed for indicating the mode of operation of thelocator unit 18, such as when thelocator unit 18 is in air mode as will be discussed hereinafter. Anemergency button 42 is provided on theportable locator unit 18. Activation of theemergency button 42 initiates a communication with thecentral station 12 whereby a signal indicating an emergency situation exists is transmitted by theportable locator unit 18. In response to the receipt of the emergency signal, thecentral station 12 initiates the process of locating theportable locator unit 18 and upon determining the location alerts the proper emergency personnel. Anon-emergency location button 44 is also located on theface side 40 of theportable locator unit 18. Activation of thenon-emergency location button 44 contacts thecentral station 12 for locating theportable locator unit 18. Upon locating theportable locator unit 18, thecentral station 12 contacts a predetermined party to inform them of the location of theportable locator unit 18. Anair mode button 46 is also provided on theportable locator unit 18. Theair mode button 46 turns off thetracking device 18 for a predetermined period of time. This mode is useful when entering areas where the use of cellular technology is prohibited, such as on an airplane. - A side view of the
portable locator unit 18 is shown in FIG. 3. From this figure, thelatching mechanism 48 is shown along with alock button 50, a port 51 for Key Fob and aport 52 for receiving a headphone. Theportable locator unit 18 is secured (locked) to the wearer by latching thelatching mechanism 48 and connecting a Key Fob to lock theportable locator unit 18 by pressing thelock button 50 on the Key Fob. Theportable locator unit 18 could also be locked by a command from thecentral station 12. The lock/unlock button on a Key Fob activates an electromechanical device by uploading one of 1E22 different key codes to theportable locator unit 18, instructing it to latch a dead bolt, which prevents theportable locator unit 18 from being unlatched and removed. Upon activating the lock throughbutton 50 or the Key Fob, thelock icon 41 appears on thedisplay 36. The data indicating the lock/unlock status is contained within a data package when theportable locator unit 18 is communicating with thecentral station 12. Theportable locator unit 18 can also be attached (not locked) to the user by simply latching thelatching mechanism 48 and omitting the locking procedure. Once the latch is locked, it can be unlocked only by an authorized Key Fob. When theportable locator unit 18 is unlocked, the lock icon disappears from thedisplay 36 and theportable locator unit 18 is able to be unlatched and removed. In order to minimize battery consumption at theportable locator unit 18, the preferred embodiment utilizes an IS95B PCS for communications between theportable locator unit 18 andcentral station 12. Anexemplary locking mechanism 48 is illustrated in FIG. 3. However, thelocking mechanism 38 may be provided with a variety of possible locking mechanisms such as keys, combination locks, electronic locks, etc. as long as thelocking mechanism 48 prevents theportable locator unit 18 from being detached from the item or person once attached. - A block diagram illustrating the internal components of the
locator unit 18 is shown in FIG. 4. Positioned within thelocator unit 18 and controlling operation thereof is aprocessor 54. Connected to theprocessor 54 and providing power to thelocator unit 18 is aninternal power source 56. Abattery sensor 58 is connected between theprocessor 54 andpower source 56. Thebattery sensor 58 senses the power of the power source and provides a battery power signal to theprocessor 54. Theprocessor 54 is thus able to determine when the power level is low and operate accordingly. Amemory 60 is provided for storing data processed by theprocessor 54 and programs used by theprocessor 54 for operation of thelocator unit 18. Areceiver 62 is provided for receiving wirelessly transmitted signals from thecentral station 12 and atransmitter 64 transmits signals to thecentral station 12. Both thereceiver 62 andtransmitter 64 are connected to and controlled by theprocessor 54. Amicrophone 66 andspeaker 68 are also provided for establishing a voice communication with another party through thecentral station 12. Alternatively, the microphone and speaker may be contained within a headset connected to thelocator unit 18 through theheadphone port 52. Themicrophone 66 is able to receive voice communication from the user and transmit an audio signal to the other party via thecentral station 12 using the transmitter. Thereceiver 62 is able to receive audio signals from thecentral station 12 for reproduction through thespeaker 68. - A
GPS receiver 70 is provided for contacting theGPS satellite 14 in order to determine a location of thelocator unit 18. The location information is provided to theprocessor 54 and eventually to thecentral station 12. Abeacon generating device 72 generates a sonic or radio frequency beacon for aiding in locating the user when at close range. Thebeacon generator 72 can be enabled for final approach to the wearer if a situation requires physical contact for rescue or any other reasons. In general, the GPS system does not have enough resolution to pinpoint a wearer within a building or visually obstructed area. Thebeacon 72 provides a means to achieve the final approach using a sonic or radio frequency device. Akey fob 74 provides an additional means for securing thelocator unit 18 about the wrist of the user. The Key Fob also provides a mechanism for charging a battery inside thelocator unit 18. Atamper sensor 76 detects when thelocator unit 18 has been tampered with or cut and signals theprocessor 54 of such. Theprocessor 54 then generates an emergency signal which is transmitted to thecentral station 12. Thecentral station 12 initiates a communication with thelocator unit 18 for locating thelocator unit 18. Thepanic button 42 andnon-emergency call button 44 are connected to theprocessor 54 for initiating communication with the central station upon activation. Thedisplay 36 is also connected to theprocessor 54. Theprocessor 54 controls the icons and the clock viewable on thedisplay 36. - The operation of the personal
location detection system 10 will now be described with reference to the figures and specifically FIGS. 5 and 6. In operation, the personallocation detection system 10 is used to locate a person or object to which thelocator unit 18 is secured. Shown in FIG. 6 is an example of PCS network basedlocator system 10. Thelocator unit 18 includes aGPS unit 70, aPCS communication system processor 54. Thecommunication system 86 includes a processor therein for analyzing signals received by the receiver of thecommunication system subscriber 78, typically a guardian in a missing child case, normally initiates a locate process through a regular phone (PSTN), awireless telephone 80 or aninternet connection 82. An operator in thecentral station 12 receives the request and initiates a call set up with thelocator unit 18. Theuser 20 can also initiate a call set up by pressing either thepanic button 42 or thenon-emergency call button 44. In this instance, thelocator unit 18 contacts thecentral station 12 and the system operates similarly to when asubscriber 78 contacts thecentral station 12. - The
communication system communication system control station 12 and sets up a communication link upon receipt of a request from thecontrol station 12. The request from thecontrol station 12 passes through the public service telephone network (PSTN) or cellular 80 and is received by the receiver ofcommunications system locator unit 18 for analysis by thecommunications system 86. Thelocator unit 18 then responds to the request and transmits a response signal via the transmitter of thecommunication system communication system control station 12 when an event counter triggers thecommunication system central station 12 and thelocator unit 18. Thecommunication system device Key Fob 74 for secure lock/unlock and battery charging operations. - The
GPS unit 70 performs the locating operation utilizing signals from theGPS satellites 14 in a view. Normally, theGPS unit 70 is in powered off mode, in response to a command from thecentral station 12 or upon activation of either thepanic button 42 ornon-emergency call button 44, theGPS unit 70 is turned on and starts the locating process upon activation by theprocessor 54. TheGPS unit 70 can utilize aiding information from thecentral station 12 for improved performance. Such aiding information includes but is not limited to the approximate location of thelocator unit 18, an almanac, ephemeris, a frequency offset, doppler, reference time, etc. TheGPS unit 70 provides the location data computed using theGPS satellite 14 to theprocessor 54. Theprocessor 54 initiates a call to thecentral station 12 and provides the location data to thecentral station 12 for analysis. Thecentral station 12 is thus able to determine the location of thelocator unit 18 to within a reasonable area. Theprocessor 54 then activates thebeacon generator 72, if necessary, to generate a sonic or radio frequency signal which a allows final approach to a desired object even within the area where the GPS or wireless communication link can not be established due to obtruded environment. - FIG. 5 illustrates a state diagrams showing different operating modes of the system for obtaining the location of the
locator unit 18. Initially, thelocator unit 18 is in a watch mode. During the watch mode, thelocator unit 18 monitors for incoming signals from thecentral station 12. Upon receipt of a signal from a subscriber or from thelocator unit 18 in response to activation of thepanic button 42 ornon-emergency call button 44, thecentral station 12 sends an SMS (Short Message Service) Message to thelocator unit 18 which requests that thelocator unit 18 contact thecentral station 12. Thelocator unit 18 then initiates a QNC (Quick Net Connect) Internet session connecting it to thecentral station 12. At this time thelocator unit 18 enters the Air Time mode. In air time mode, thecentral station 12 requests that thelocator unit 18 identify its position. While thelocator unit 18 is connected to thecentral station 12, the required information to assist theGPS device 70 in locating thesatellites 14 is uploaded to thelocator unit 18. Thelocation device 18 also has the capability of obtaining the required information directly from theGPS satellites 14, but this is used only as a last alternative measure. Thelocator unit 18 disconnects itself from thecentral station 12 and starts the process of obtaining its location. TheGPS 70 which is always off, is turned on and a precision time is transferred to thelocator unit 18 from thePCS tower 86 along with phase-locking theGPS 70 to the PCS towers 86. The voltage information of the VCO (voltage controlled oscillator) in phase locking loop (PLL) is used as an aiding information for GPS, even when the PLL is not in locking state with the PCS tower. All the aiding information available is then delivered from the communication system to theGPS unit 70 so thelocator unit 18 can use it to locate its position. After theGPS unit 70 identifies the location of thelocator unit 18, the location information is transferred to theprocessor 54 and theGPS unit 70 is shut down. The PCS Processor initiates another QNC Internet session. During this communication thecentral station 12 downloads all location information from within thelocator unit 18 and closes the session. Thecentral station 12 now knows the location of thelocator unit 18 and is capable of converting this data to coordinate information through the internet or regular communication schemes which average customers can comprehend. Thelocator unit 18 then returns to the watch mode awaiting a next signal from thecontrol station 12. Thecentral station 12 uses the location data received from thelocator unit 18 and converts it to geographic data including landmarks, which can be delivered to the subscriber on the phone or displayed on a map for Internet users. - The
locator unit 18 can be programmed to allow the wearer to initiate an emergency locate session. When the user activates thepanic button 42, thelocator unit 18 contacts thecentral station 12 indicating emergency action is required. The panic (Alert)button 42 makes the state transition from Watch Mode to Air Time Mode and an internet session is established. Thecentral station 12 notes this emergency contact and starts the locating process as described above. The initial message from thecentral station 12 includes the base station identification information which is used to indicate which of the appropriate PSATs (Public Service Answering Point) to tie into the emergency session when final location information is received. If thelocator unit 18 does not reply in a reasonable period of time, the PSAP is notified of the emergency request with no response. The air time mode then proceeds as discussed above. - A non-emergency situation call may also be initiated by the user upon activating the
non-emergency call button 44. The process followed is similar to that when thepanic button 42 is activated. When thenon-emergency call button 44 is activated, thecentral station 12 forwards this non-emergency situation information to a contact person in a prioritized contact list. This list is preferably provided to thecentral station 12 during service registration and allows contacting a guardian without a PSAT 911 emergency call center involved. - The pager mode is also illustrated in FIG. 5. The
locator unit 18 has the optional ability to display SMS messages on thedisplay 36 as a pager if a subscriber elects. In such a case, the Watch mode switches to the Pager mode upon receipt of an appropriate SMS message from thecentral station 12. The unit has a visual note such as a musical note as well as a sonic alert to notify the wearer that a page has been received. Thelocator unit 18 then displays the received pager message on thedisplay 36. - Optionally, the
locator unit 18 is able to receive wired or short range wireless communications to and from a headset/microphone which is received by theheadphone port 52 to facilitate cellular communications as PCS phone. Since there is no keypad, the wearer would initiate an internet session, which connects thelocator unit 18 to thecentral station 12 computer. Thecentral station 12 computers have voice recognition software which, when prompted, initiate a call forward to wherever the user requests. Thelocator unit 18 should be in the Air Time Mode during phone communication. - In order to comply with the FCC's requirement to have a cell phones turned off during air travel, the
locator unit 18 is capable of being temporarily shut off by using an authorizedKey Fob 46 to shut down the cellular phone circuitry for a specified period of time (from 1 to 24 hours) as set by the user. After this time expires, thelocator unit 18 automatically turns on and waits to be called in low power mode. An icon indicating thelocator unit 18 is in airplane mode as well as the remaining time until reactivation will be displayed. Additional time can be incremented (or set to zero) if desired through reconnecting the Key Fob. -
Key Fobs 74 are used for unlocking and locking thelocator unit 18 about the wrist of the user. The Key Fob also contains the battery charging circuitry which, when connected to a wall voltage through the supplied transformer, (to the same port that is used to unlock the locator unit 18), will charge thelocator unit 18. Any Key Fob can charge thelocator unit 18 but only an authorized Key Fob can unlock or activate the Airplane Mode. Other Key Fobs can be added to be used as authorized or unauthorized charging fobs only for use of the wearer if they are to be away for extended periods. A car battery adapter can also be used with the Key Fob to charge while traveling. Eachlocator unit 18 can also be programmed to allow up to a predetermined number of key fobs. A single Key Fob can open asmany locator units 18 as it has been programmed with no limit. The Key Fob and transformer (battery charger) can be used as a backup method to unlock thelocator unit 18 if the battery is depleted to a value too low to open the lock. Additional key fobs can be authorized to the unit via thecentral station 12 in an over-the-air activation process. - The display has the ability to display time, date, page number, or page data. Furthermore, various icons display status of the
locator unit 18 or current mode of operations such as antenna signal strength, lock indicator, Audio mode for page alert, Airplane mode, battery charge level indicator, etc. - The
locator unit 18 has tamper and cutdetection circuitry 76 which activates a self initiated emergency session which detected that will indicate tampering. If thelocator unit 18 is tampered with while not being worn, an alarm signal is generated as soon as it is locked on the wearer. - Ephemeris data is downloaded from the
satellites 14 nationwide by thecentral station 12 as indicated by numeral 25 in FIG. 6 for delivery to thelocator unit 18 as required. These ephemeredes are time sensitive and do change continuously. Therefore, this data needs to be constantly refreshes at thecentral station 12 so it is available at all times. - The locator unit's18
CDMA processor 54 acts as a thin server to the locator unit's GPS. Due to the limited power available with thepower source 56, the GPS receiver is turned off when it is not finding satellites. The GPS when turned on goes through a power up routine, and, since the crystal on the GPS is not adequately warmed up, the drift makes it unsuitable to be used to find the satellites. The system of the present invention synchronizes the frequency of the GPS with the PCS tower frequency. Even though they are different frequencies it is consistent and the phase lock frequency error can be programmed into the GPS software to achieve an accelerated frequency search algorithm. The time accuracy also requires a higher accuracy than what can be supplied in the mobile unit. The required GPS time accuracy is transferred from thePCS tower 22. This could have an error of up to 100 μsec due to the variability of distance from thePCS tower 22 andlocator unit 18. The 3-sigma point is then calculated and the time error and this accuracy are used as the seed time for starting the search of the variability from the tower. Since time to first fix is of utmost importance we do not use the GPS as the primary means (backup only when not available from PCS tower) to download the ephermeris from thesatellites 14. The PCS phone communications to thecentral station 12 includes the base station identification number (ID) associated with the location of thetower 22, allowing thecentral station 12 to select only thosesatellites 14 visible to thelocator unit 18 for the next ephemeris period. The GPS also knows when an ephemeris for aparticular satellite 14 is invalid and will eliminate it from its search string. - From the above description it can be seen that the personal location detection system of the present invention is able to overcome the shortcomings of prior art devices by providing a personal location detection system which is able to track a missing person in both hostile and non-hostile situations, using the Global Positioning Satellite system (GPS) to determine the location of the user with limited battery power resources. The personal location detection system includes a portable locator device including a communication device for wirelessly connecting to both a communications network and the GPS system and relaying the location determined by the GPS system to a central station via the communications network. The portable locator unit is able to generate a sonic or radio frequency beacon for aiding emergency personnel in pin pointing the location of the user, initiate an emergency call to the central station, whereby, in response to the call, the central station will contact a designated person as to the location and situation regarding the user. The portable locator unit is also able to initiate a non-emergency call to the central station, causing the central station to contact a designated person and initiate a voice call to another party via the central station using the locator unit. Furthermore, the personal location detection system of the present invention is simple and easy to use and economical in cost to manufacture.
