Paper Abstract

With the needs of growing location-based service, a more high-performance satellite positioning technology - assisted global navigation satellite system (A-GNSS assisted-GNSS) becomes a new hotspot in area of navigation and positioning. Now, 3GPP has already provided supports for GPS, Galileo, GLONASS and QZSS, SBAS, so standardization work of introduction BDS into 3GPP organization is very imperative. In this paper, we first analysis the performance of GPS L1 C/A with assistant information, then by taking into account the difference between BDS and GPS, including the unique nature of GEO/NGEO satellites’ navigation message data length and format, we design the sensitivity requirements of BDS B1 following A-GPS. The results between A-GPS and A-BDS of typical sensitivity test cases are shown in this paper, which show that the suggested sensitivity requirements satisfy the minimum performance requirements under technical specification of 3GPP TS 36.171.
