Embodiment Construction

[0017] In order to make the objectives and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0018] Such as figure 1 As shown in the embodiment of the present invention, a multi-route inter-satellite communication link based on cluster formation is provided. The multi-route inter-satellite communication link is dedicated to omnidirectional It consists of a communication antenna for signal transmission and reception, an inter-satellite terminal dedicated to multi-channel search / capture / tracking, and a processor dedicated to pre-processing work such as inter-satellite data reception and filtering; the multi-route inter-satellite communication link adopts multi-channel Parallel acquisition technology searches for the same cluster satell...

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...
