- This paper presents the carrier phase DGPS method providing a stable navigation solution under the condition of frequent blockage of the GPS signa ls. The proposed
algorithm reject the channels having large errors usin g a clock bias dr ift and then
calculated the more accurate solution. By investigating the relation between visible
satellites' elevation and their clock bias dr ift, a proper thr eshold is set. Simulation shows that the presented result is as good as that of commercial system with real data.
