Technology Information Sharing,e satellite ., . is the geometric distance between the satellite and the observing point, and . is the speed of light. The last item to be explained is Δδ.(.). This clock bias represents the combined clock offsets of the receiver and the satellite clock with respect to GPS time, cf. Eq. (6.1).

Observables,d 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.

Applications of GPS,st every day. In this chapter, an arbitrary grouping of global, regional, and local uses has been selected. A further additional arbitrary classification of navigation and survey uses is made to help organize the discussion of GPS applications.
