Abstract

After the implementation of BEIDOU Constellation Satellites in 2003,the planned navigation and positional functions are basically acceptable.As one of the co-investors in the GALILEO navigation and positional system,it is impending and necessary for China to consider how to integrate and incorporate the two navigation systems,namely,the BEIDOU and the GALILEO.Herein,taking into account the both navigation systems,the PDOP for this hybrid navigation system is simulated.The PDOP for domestic typical cities are presented.Simulations have showed that regional improvement are obvious,however the global improvement is limited.
