ZHANG Zhi-rong, FAN Sheng-lin, LIU Jian-ye. Study on performance of combined GPS and Galileo positioning[J]. 2007, (9): 7-10. DOI: 10.13873/j.1000-97872007.09.002.
The differences of the GPS and Galileo system are investigated and the solutions for the differences are given.By using an user track
the positioning performance of the GPS
Galileo and the combined one is studied
and also the positioning performance such as the number of the visible satellite and the PDOP value in the region of China and the Nanjing University of Aeronautics and Astronautics(NUAA)standard point is studied.The results show that the positioning performance of the combined system is perfect and the GPS-Galieo combined system is practicable.
