Multi-route 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 multi-route inter-satellite communication link based on a cluster formation. Background technique [0002] In order to meet the needs of inter-satellite multi-route communication for multi-satellite cluster formation, the related inter-satellite communication link multi-route communication technology design is developed for the needs of queue communication and multi-satellite communication. [0003] There are many design schemes of inter-satellite communication links available for reference at home and abroad, but these inter-satellite links are suitable for a small number of satellite inter-satellite communications or their multi-satellite inter-satellite links have the same orientation, or can only be visible to the field of view. For communication, large inter-satellite forwarding delay, or inter-satellite link gap work between multiple satellites, none of them meets the current needs of mul...
