ABSTRACT:
A method for estimating two or three location coordinates and/or receiver time offset for a receiver that receives and analyzes timed signals transmitted from one, two or three non-geosynchronous satellites (GPS, GLONASS, modified LEO, etc.). Combinations of pseudorange, Doppler shift and/or first time derivative and/or second time derivative of Doppler shift are determined and used to estimate the location coordinates and/or receiver time offset.
