Relativistic effects in GPS,t of up to 0.001 ppm in positioning. The second part affects the clock frequency on the order of 10., but only the periodic fluctuation in it is of interest. This term is completely canceled out by between-station differences, hence it is harmless for relative positioning, but it directly affects th

The use of GPS at IGN : Geodesy, geophysics, engineering, production purpose, a specific software, called GDVS, was then developed. This software is now operational and has been used with success to process several GPS campaigns..Two major campaigns were performed in 1986 : one between France and England and the second one between France and Italy. One of

Investigation of an alternate method of processing global positioning survey data collected in kinermined. Two experimental results are presented. A byproduct of the reduction was the generation of a measure of success similar to the Geometrical Dilution of Precision (GDOP) familiar to those using measurements of pseudo ranges. This new measure is called RDOP for Relative Dilution of Precision.

Experiences with the WM 101 GPS receiver,PoPS software in some campaigns and pilot projects, such as the GPS test network at Gävle, a densification network in the Båstad region, the triangle RIT-Lovön-Uppsala, height control for photogrammetric mapping and the Åland campaign. The experience gained until now is summarized in the presentatio

Experiences with TRIMBLE receivers in the control network of the F. R. G.,ication network..In this report first experiences are given with investigations about the accuracy of short distances (<10 km), the organisation of field work, the design of the network, the costs and the organisation of the evaluations.

Campaigns with WM101 in Austria 1987,swer mainly three questions:.The three campaigns have shown that in most cases we can answer these questions in a positive way. The precision of WM-101 seems to lie at the 1–2 ppm level for distances ranging from 5 km to 50 km.
