- W3204207309 abstract "Beidou navigation satellite system (BDS) is a global navigation satellite system independently constructed and operated by China. An important function of BDS is to have autonomous navigation capability. Satellite autonomous navigation is a kind of satellite navigation technology that can operate autonomously without the support of ground system. Based on the inter-satellite ranging information, the navigation message information is generated independently and broadcast to users, so as to realize real-time navigation, positioning and timing. The systematic deviation of autonomous navigation message is the deviation between the calculated value of ephemeris and clock and the observed value, which is recorded as o-c. It reflects the matching degree between navigation message and inter-satellite observation. Theoretically, the smaller the better. Aiming at the systematic deviation of autonomous navigation message, this paper proposes a calculation method to eliminate the systematic deviation. Experiments show that this method can effectively reduce the message system error of autonomous navigation, that improve the performance of autonomous navigation." @default.
