1. 1 Error Categories 1. Errors related to GPs Satellites 2. Errors related to GPS signal propagation

Perigee and Apogee: The point of closest approach of the satellite with respect to the earth's center of mass is called perigee and the most distant position is the apogee. Nodes: The intersection between the equatorial and the nit sphere is termed the nodes, where the ascending node defines the northward
