While the major use of GPS to most geodesists involves the use of two or more receivers in interferometric mode, it is very important to keep in mind the reason GPS was developed in the first place — to determine at an instant the location of a soldier, ship, plane, helicopter, etc. without any equipment other than a single GPS receiver and antenna. This is often referred to as absolute positioning. Without satisfying this requirement, there would be no GPS. Thus it is important that some time and effort be spent in the study of single-site modeling. In this chapter, the processing techniques using the pseudorange measurement are discussed. Also the combination of pseudorange and carrier phase are introduced.
