Generally speaking, the methods known so far contain advantages and disadvantages as well..Preprocessing methods are presented permitting cycle-slip detection in a two-step procedure. After setting-up a testing quantity its behaviour is checked with respect to smoothne

A Comparison of Several Techniques to Reduce Signal Multipath from the Global Positioning Systemrement. The multipath environments are compared by computing the standard deviations from the pseudorange measurements over several hours. These have ranged from 1.3 m in a benign environment to 4.0 and 5.0 m in a highly reflective environment..This paper presents the results of several tests of pro

Two short baselines (400 and 100 m) observed for one hour with the TRIMBLE microstrip antenna were selected to illustrate limitations resulting from multipath in an urban environment. Baseline c

A complete understanding of the crustal motion of a particular region requires a dense set of geodetic measurements in space and time.

Some First Experiences with the WM102 GPS Receiver were carried out. The practical experiences of these campaigns are reported. The overall experience of the receivers is that they are both reliable and easy to operate. The preliminary results for baselines with different lengths (long, medium and very short) are generally satisfactory, but signifi
