Base station

Also called a reference station, is a receiver located at a surveyed benchmark. The base station calculates the error for each satellite and through differential correction, improves the accuracy of GPS positions collected at unknown locations by a roving GPS receiver.

Geosynchronous satellite

A satellite moving west to east whose orbital period is equal to the earth’s rotational period. If the orbit is circular and lies in the plane of the equator, the satellite will remain over one point. Otherwise it will appear to make a figure eight once a day between the latitudes that correspond to its angle of inclination over the equator. The constellation for GPS is geosynchronous.


A collection of different pieces of georeferenced information (yield, soil type, fertility) that can be manipulated (layered) in a GIS model.


(GPS) The measure of closeness of an object's actual (true) position to the position obtained with a GPS receiver. Accuracy levels are used to rate the quality of GPS receivers.
