Beschreibung
Zusammenfassung:	A system, method and apparatus is provided for calculating the position of a single receiver by receiving a signal from an emitter. Either the receiver or the emitter may be stationary relative to the surface of the Earth. The invention may use a particle filter to optimize the efficiency of the position calculation. The invention may further utilize a particle filter to estimate the frequency drift and bias of the emitter and/or receiver, and use the estimated frequency drift to improve the position calculation. In one embodiment, the invention may be used to calculate the position of a single GPS receiver given the position of, and a transmission from, a single GPS satellite.
