Abstract Precise point positioning (PPP) accuracy of compass and GPS was compared using the data from Rongcheng,Xiaguan,Yanchi,Tangshan and Zhenzhou,with PANDA software.The results show that: Beidou navigation PPP accuracy in horizontal direction is 12 cm,in vertical direction is 34 cm;GPS PPP accuracy in horizontal is less than 1 cm,and in vertical direction is about 12 cm.Although the PPP accuracy of the Beidou navigation system is 50% lower than the PPP accuracy of GPS,it is suitable for use in the fields in which requirement of accuracy is not high.
Key words :
Beidou navigation system
GPS
