AbstractAccurate GPS vector determination is nowadays one o/ the major problems in modern geodesy. Most o/ the errors are modelled either to smooth atmospheric ejJects or to remove biases, like clock offsets. The network design criteria and the vector processing solutions are based in distances to the reference stations and in the time span o/ the vectors involved in the sessions. Thus, the final solutions are computed accurately and the residuals show the quality o/ the computations. What is not usual to be taken into account in the final vector computation is the bearing o/ the vector to be processed, as the cutoff angle is considered fixed. This paper deals with the variation on the final solution due to the different cutojJ angles, and still more important, to the bearing o/ the vector in high precision GPS vector determination. If in the future, the IGS starts to distribute orbits that are created using the ANTEXfile, this elevation-ongle dependency should diminish.
