Abstract

An apparatus and method for locating a remote station operating in analog mode, and that may not have a sense of network time, using an inverted GPS approach. The invention also enables remote stations operating in analog mode that do not know true GPS time to determine their own location. A
time stamp, reflecting the approximate time a satellite range measurement is made, is assigned to the measurement at either the remote station or elsewhere in the network. The difference between true GPS network time and the measurement time is treated as a variable "error" in measurement, the length of which is unknown. This variable error is determined and used in determining the physical location of the remote station.
