Abstract

In order to provide GNSS positioning performance under the whole constellation for the global users, the performance of GPS, GLONASS, BDS and GALILEO multi-system constellation fusion needs to be studied. Spatial sampling is conducted according to the global latitude and longitude resolution of 5°×2.5° to evaluate the system with different cut-off angles and multi-constellation combination, including the number of visible satellites, PDOP value and PDOP availability. The results show that the PDOP availability for BDS stand-alone system under 10° cut-off angle is over 98.6%, that for dual-system under 30° cut-off angle is over 95%, and that for four-systems under 40° cut-off angle is up to 100%, dual-system and four-system fusion can significantly improve the satellite availability.

Key words： BDS; GNSS; availability; number of visible satellites; PDOP
