摘要:A geographic tracking system with minimal power and size required at the mobile terminal (8) collects obrvation data at the mobile terminal, forwards the data to a processor, which calculates the position. The mobile terminal needs only to gather a few milliconds of obrvation data, and to relay this obrvation data to the processor. The range from the satellite (13)(or other airborne transponder) to the terminal is determined using the known positions of an interrogating transmitter and a satellite (13), and a known terminal delay between the received signal and the transmission of the return signal, and the round trip time. An arc of locations is determined by computing an interction of a sphere centered at the satellite having a radius given by the calculated range with a model of the Earth's surface. Alternatively, candidate locations that are consistent with the carrier signal received from GPS satellites (14-17) can be ud. In either ca, the candidate points are considered and refined using code pha measurements from a t of GPS satellites (14-17). The candidate point having the lowest residuals or expected to measured code phas is chon as the location of the mobile terminal. The measurements can be refined to account for various sources of error including measurement bias, relative motion and timing errors.
