Description

technical field [0001] The invention relates to the technical field of remote sensing systems, in particular to a sky-link-air collaborative remote sensing system and an information transmission method thereof. Background technique [0002] With the development of remote sensing technology, the remote sensing system has changed from a single remote sensing platform to a remote sensing formation to improve the coverage, observation time and positioning accuracy of the remote sensing system. A single remote sensing platform is, for example, a remote sensing satellite, a remote sensing airship or a remote sensing The aircraft and the remote sensing formation are, for example, remote sensing satellite constellations, remote sensing airship formations, or remote sensing aircraft formations. However, when performing complex monitoring tasks, such as natural disasters, major activities, and violent terrorist incidents, the remote sensing system used to perform tasks is required to ...

AI Technical Summary

Problems solved by technology

[0005] The existing remote sensing system only relies on single-domain remote sensing platforms or single-domain remote sensing formations, which cannot meet the needs of emergency and precise remote sensing monitoring; several domain platforms cooperate according to certain rules to independently obtain remote sensing data and build a collaborative remote sensing system. The scene has great limitations
