Omnidirectional inter-satellite communication link based on double-satellite flying-around formation

Abstract

The invention discloses an omnidirectional inter-satellite communication link based on double-satellite flying-around formation. The omnidirectional inter-satellite communication link based on double-satellite flying-around formation includes an omnidirectional inter-satellite communication antenna array, radio frequency channels, an inter-satellite link management unit, and inter-satellite basebands, wherein the inter-satellite link management unit controls two channels of inter-satellite basebands to transmit-receive the data of a set of inter-satellite radio frequency channels; an inter-satellite link formed by the two channels of inter-satellite basebands, the radio frequency channels and the inter-satellite antenna link implements heterogeneous synchronous transmission and reception of inter-satellite data; the inter-satellite link of each satellite can simultaneously capture, track and select the two channels of heterogeneous signals of other satellites; the rate can be independently adjusted according to whether the current inter-satellite distance and the inter-satellite communication are normal; and configuration and control of the operating mode of the inter-satellite link can be managed synchronously by the inter-satellite link management unit. The omnidirectional inter-satellite communication link based on double-satellite flying-around formation solves the problemthat omnidirectional communication cannot be realized due to existence of a traditional omnidirectional array antenna interference zone.

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...
