MATHEMATICAL TREATMENT OF ECCENTRIC GPS-MEASUREMENTS
Satellite methods of determination of position using GPS-receiver are widely used nowadays. For geodetical use of satellite systems relative method of measurement is applied. There are some cases when it is impossible to locate GPS-receiver exactly on the centre of determined point. Then it is necessary to conduct eccentric GPS-measurements. The objective of research is obtaining the space geocentric coordinates of the point when applying eccentric measurements using GPS-receiver. The need of that it is when one conducts measurements at the points with mounted signal or pyramid. Determining of qualitative data using GPS-receivers is problematic. In metropolitan area networks eccentric measurements can be used when it is necessary to determine coordinates of wall points. Problem definition, methods of direct and indirect treatments of eccentric satellite measurements are provided. Programs for treatment of GPS-measurements are mentioned.
