ABSTRACT
Satellite positioning is the term used to describe the determination of the absolute and relative coordinates of points on (or above) the Earth's land or sea surface by processing measurements to, and/or from, artificial Earth satellites. In this context, absolute coordinates refer to the position of a point in a specified coordinate system, whereas relative coordinates refer to the position of one point with respect to another (again in a specified coordinate system). Relative positions are generally more useful in surveying and can usually be more accurately determined.
