[Abstract]:The early warning information release based on Beidou satellite is the release of early warning information by using the short message function of Beidou satellite navigation system, which can effectively improve the coverage and timeliness of early warning information release. In this paper, a new design method of communication parameters under this publishing mode is proposed. The transmission times of early warning information and the number of broadcast ID of command aircraft are two important communication parameters that need to be determined in the early warning information publishing mode based on Beidou satellite. The quantitative analysis shows that with the decrease of transmission success rate threshold or the number of subpackets of early warning information, the optimal transmission frequency of early warning information decreases in the form of ladder, and with the increase of release time, the optimal broadcast ID number of command aircraft decreases approximately linearly. With the decrease of transmission success rate threshold or the number of subpackets of early warning information, the optimal broadcast ID number of command aircraft decreases in the form of ladder. The communication parameter design method proposed in this paper can be used as a reference for index calculation in the design of early warning information publishing system based on Beidou satellite.
