Geometric Dilution of Precision (GDOP) value will become larger when the number of visible satellites is less than four or the geometry of satellite constellation is poor, a GDOP Chimney Peak phenomenon is also easy to emerge [, the positioning accuracy of GPS receiver will be affected seriously. A vector-based tracking loop GPS/INS receiver design method is proposed in this paper. The current position of receiver is given by INS, Line-of-Sight (LOS) unit vectors between receiver and satellites will be built, which are transmitted into vector tracking loop, the relationship between LOS and GDOP is introduced in detail. Pseudorange and pseudorange-rate are used as measurements to design navigation filter. The simulation results demonstrate that proposed vector tracking method can avoid GDOP Chimney Peak phenomenon, position Root Mean Square error is less than 10 meters.

And Performance

A number of methods have been developed to enhance the robustness of Global Positioning System (GPS) receivers when there are a limited number of visible satellites. Vector tracking is one of them. It utilizes information from all channels to aid the processing of individual channels to generate receiver positions and velocities. This paper analyzes relationships among code phase, carrier frequency, and receiver position and velocity, and presents a vector loop-tracking algorithm using an Extended Kalman filter implemented in a Matlab-based GPS software receiver. Simulated GPS signals are generated to test the proposed vector tracking method. The results show that when some of the satellites are blocked, the vector tracking loop provides better carrier frequency tracking results for the blocked signals and produces more accurate navigation solutions compared with traditional scalar tracking loops.
