Abstract
In concept, the GPS observables are ranges which are deduced from measured time or phase differences based on a comparison between received signals and receiver generated signals. Unlike the terrestrial electronic distance measurements, GPS uses the “one way concept” where two clocks are used, namely one in the satellite and the other in the receiver. Thus, the ranges are biased by satellite and receiver clock errors and, consequently, they are denoted as pseudoranges.
