Abstract: The existing satellite communication vehicles have complex configuration and long process, and must rely on the existing communication channels to negotiate the parameters. In order to solve the above problems, this paper designs a fast networking scheme for the satellite communication vehicle using the Beidou short message. This paper gives a detailed and detailed scheme, and the hardware structure of the selfcontrollable vehicle central control unit, the reliable transmission protocol of the Beidou short message, the data transmission format and the mechanism of pingpong use of double Beidou terminal are designed. The solution of this paper effectively solves the malpractice of the satellite communication vehicle and achieves rapid networking.
