Peggy Pelonis,Thimios ZaharopoulosLos Angeles Air Force Base (AFB). In 1973, the JPO was directed by the U.S. Department of Defense (DoD) to establish, develop, test, acquire, and deploy a spaceborne positioning system. The present Navigation System with Timing And Ranging (NAVSTAR) Global Positioning System (GPS) is the result of this initial directive.

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.

The last item to be explained is..This clock bias represents the combined clock offsets of the satellite and the receiver clock with respect to GPS time, cf. Eq. (6.1).
