| 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 applications and what will be the resulting accuracy. A test rig has been specifically manufactured to produce centrifugal 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. The accuracy of the GNSS receiver was measured considering different parameters such as baseline length, radius of rotation and processing software. Also, the lose-of- signal lock was detected in each case. The research revealed that the GNSS receiver has very promising potential for use in high dynamic applications. | ||
