Abstract
Determining the three dimensional coordinates of points by communication with satellites has always inspired scientists and researchers. Primarily, GNSS were used in a static or semi static mode if high accuracy is required. However, as a result of the substantial improvement made in the capabilities of the satellites and the signal structure, it was important to investigate methods of improving the accuracy obtained from these systems when used in high dynamic environment which is of great importance for many applications. The purpose of this research is to investigate how far GNSS receivers could be used in such high dynamic application and what will be the resulting accuracy. Two test rigs have been specifically manufactured to produce both centrifugal and reciprocating motion to simulate the GNSS movements when used in high dynamic mode such as unmanned vehicles, ground motion during natural hazards or movements of high-rise building. Also, a field test was made to check the tracking capability of the receiver during horizontal planed motion by fixing the receiver on a car moving at very high speeds up to 150 Km/h. The change of the number of satellites locked by the receiver in this high dynamic mode was detected. The research revealed that the GNSS receiver has very promising potential for use in high dynamic applications.
