A multi-routing inter-satellite communication link based on cluster formation

Abstract

The invention discloses a multi-route inter-satellite communication link based on cluster formation. The multi-route inter-satellite communication link based on the cluster formation is composed of acommunication antenna which is exclusively used for omnidirectional signal transmitting and receiving; inter-satellite terminal machines which are exclusively used for multichannel searching / capturing / capturing; and processor which are exclusively used for inter-satellite data transmitting and receiving and screening. According to the multi-route inter-satellite communication link, through adoption of a multichannel parallel capturing technology, the same cluster satellite signal is searched; through utilization of a queue type multi-route communication technology, inter-satellite informationof all satellites in a cluster is directly or indirectly switched; through adoption of a forwarding delay dynamic optimization technology, the processors determine transmitting opportunity according to priority of current data and reduce forwarding delay of important data to the lowest; and a multiway information optimization technology is employed. According to the multi-route inter-satellite communication link, the problem that a traditional inter-satellite communication scheme is few in access terminal number, serious in dependence on antenna visibility and long in forwarding delay is solved.

Description

technical field [0001] The invention relates to an aerospace vehicle, in particular to a cluster formation-based multi-routing inter-satellite communication link. Background technique [0002] In order to meet the needs of inter-satellite multi-route communication for multi-satellite cluster formations, the design of inter-satellite communication link multi-route communication technology is carried out for the requirements of queue communication and multi-satellite communication. [0003] There are many inter-satellite communication link design schemes available for reference at home and abroad, but these inter-satellite links are suitable for inter-satellite communication with a small number of satellites or multi-satellite inter-satellite links with constant direction, or only for visible stars in the field of view. Communication, or the forwarding delay between multiple stars is relatively large, or the inter-satellite link gap between multiple stars does not meet the cur...
