ABSTRACT
Currently, there are many cases of batch production of satellite payloads. In order to achieve universal compatibility with any satellite, a method of dynamically configuring the payload identity ID through software settings has been proposed. This paper mainly focuses on the research of the star-carried CAN bus communication principle and testing methods with dynamically configurable IDs. By setting a digital combination (nID) to identify the local device, communication with the onboard computer is established, and the correctness of communication is ensured through physical layer, data link layer, and application layer testing. These testing methods are of great reference value for the design and validation of software for star-carried CAN bus.

Analysis of satellite-induced factors affecting the accuracy of the BDS satellite differential code bias
Differential code bias (DCB) is one of the main error sources of the positioning, navigation and timing services and slant total electron content extraction. The DCB can usually be estimated together with ionospheric model coefficients from the data of ...
Precise orbit determination for BDS-3 satellites using satellite-ground and inter-satellite link observations
Since November 2017, eight BeiDou global navigation system (BDS-3) satellites equipped with Ka-band inter-satellite link (ISL) payloads have been launched into medium earth orbit. We present the precise orbit determination (POD) for BDS-3 satellites ...
