Abstract

The invention discloses an omnidirectional inter-satellite communication link based on double-star fly-around formation, including an omnidirectional inter-satellite communication antenna array, a radio frequency channel, an inter-satellite link management unit, an inter-satellite baseband, and an inter-satellite link management unit Control the 2-way inter-satellite baseband to send and receive data of a group of inter-satellite radio frequency channels, and the inter-satellite link composed of the 2-way inter-satellite baseband, radio frequency channel, and inter-satellite antenna realizes the heterogeneous synchronous transmission and reception of inter-satellite data; The inter-satellite link of a satellite can capture, track and select two heterogeneous signals of other satellites at the same time; and can independently adjust the rate according to the current inter-satellite distance and whether the inter-satellite communication is normal; the work of the inter-satellite link The mode configuration and control are managed synchronously by the inter-satellite link management unit. The invention solves the problem that the omnidirectional communication cannot be performed due to the existence of the interference area of ​​the traditional omnidirectional array antenna.

Description

technical field [0001] The invention relates to an aerospace vehicle, in particular to an omnidirectional inter-satellite communication link based on a formation flying around two stars. Background technique [0002] In order to meet the needs of inter-satellite communication for double-satellite formations used in orbiting formations, the design of the related omnidirectional inter-satellite communication link is carried out for the needs of omnidirectional and full-time communication. [0003] There are many design schemes of inter-satellite communication links that have been realized at home and abroad, but these inter-satellite links are based on the directional, intermittent, and simplex communication links of follow-up and accompanying formations, which cannot meet the omnidirectional, Full-time, duplex inter-satellite communication needs. The traditional measurement and control scheme, because of its quasi-omnidirectional characteristics, that is, the existence of th...
