Satellite orbits,The applications of GPS depend substantially on knowing the satellite orbits. For single receiver positioning an orbital error is strongly correlated with the positional error. In relative positioning (according to a rule of thumb) relative baseline errors are equal to relative orbital errors.

Applications of GPS,The general overall uses of GPS are numerous. 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.

Marko N. Živanović,Nenad FilipovićLos 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.

Paula Hamilton,Chandrika Devarakonda observing site:.In Eq. (3.1) both vectors must be expressed in a uniform coordinate system. The definition of a three-dimensional Cartesian system requires a convention for the orientation of the axes and for the position of the origin.

https://doi.org/10.1007/978-981-97-3640-9d 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.
