Inter-satellite communication integration method and device for low-earth-orbit-satellite and other high-earth-orbit satellites and low-earth-orbit satellites

Abstract

The invention provides an inter-satellite communication integration method and device for a low-earth-orbit satellite and other high-earth-orbit satellites and low-earth-orbit satellites. Inter-satellite communication baseband processing and radio frequency processing of the low-earth-orbit satellite and other high-earth-orbit satellites and low-earth-orbit satellites are simultaneously realized in one piece of equipment; reusability design for an inter-satellite link antenna function and a data transmission antenna of the low-earth-orbit satellite is performed, and reusability design for inter-satellite link antenna functions and relay data transmission antennas of the high-earth-orbit satellites is performed, thereby finishing establishment of a low-orbit-low-orbit and low-orbit-high-orbit bidirectional link. The method has the advantages of being simple in engineering implementation and flexible in on-orbit application, and provides reference and basis for design of a future inter-satellite communication system of the satellites.

Description

technical field [0001] The invention belongs to the field of satellite data transmission, and in particular relates to a method and equipment for inter-satellite communication integration between a low-orbit satellite and other high- and low-orbit satellites. In particular, it relates to an integrated design method for inter-satellite communication between a low-orbit satellite and other high-orbit and low-orbit satellites. Background technique [0002] With the rapid development and application of aerospace technology, the traditional single-satellite independent working mode has become increasingly difficult to meet the application requirements due to its limited detection and communication areas. The satellite network composed of low-orbit satellites and high-orbit satellites can realize the complementary advantages of the two orbital altitude satellites, and has the advantages of high space spectrum utilization and wide coverage. It is used in environmental and disaster ...

[0006] 2) "Satellite mobile communication constellation inter-satellite measurement and control system and method" 201310078200.4, the present invention proposes a satellite mobile communication constellation inter-satellite measurement and control system, which can conduct real-time, effective and reliable measurement and control of low-orbit satellites through ground measurement and control stations and high-orbit satellites , does not involve the design of inter-satellite communication between low-orbit satellites, and cannot solve the problem of integrated design of inter-satellite communication between low-orbit satellites and other high- and low-orbit satellites proposed by the present invention

[0007] Therefore, there is currently no integrated design method for inter-satellite communication between low-orbit satellites and other high- and low-orbit satellites
