A kind of communication and remote integrated satellite system

Abstract

The invention discloses a satellite system integrated with remote communication, which has the functions of inter-satellite communication, satellite-ground communication and remote sensing, including: a satellite platform and application loads of inter-satellite communication, satellite-ground communication and remote sensing mounted on the satellite platform. In the process of simultaneous inter-satellite communication, satellite-ground communication, and multi-angle, large-scale agile remote sensing of the ground, the method of increasing the degree of freedom of the load is adopted to ensure the stability of the attitude of the satellite platform. The directivity of the inter-satellite communication, satellite-ground communication and remote sensing application loads has no overlapping area, the beam range of the ground measurement and control digital transmission antenna, the beam range of the phased array antenna and the motion envelope of the front optical system have no overlapping area. In the present invention, multiple functions such as satellite remote sensing imaging, inter-satellite communication, and satellite-to-earth communication are realized on the 100-kilogram low-orbit satellite through the design of the satellite structure, and the motion load points do not interfere with each other, realizing the fusion of multiple source data to form a closed loop of intelligent perception, decision-making, and execution.

AI Technical Summary

Problems solved by technology

However, the realization of communication and remote integration in a single satellite is a technical bottleneck, because the communication link requires fixed pointing, and the pursuit of large field of view coverage in remote sensing often requires the satellite platform to maneuver, which will definitely affect the communication link.
