Abstract

The invention belongs to the field of optical remote sensing of satellites, and discloses a global multi-target all-day real-time monitoring system and method. The system comprises a motorized carriermodule, an image acquisition module, and a ground center module, wherein the motorized carrier module consists of 24 satellites uniformly distributed on 4 orbital planes; and the local time of a satellite ascending node is 10:30, and the height of an orbit is a sun-synchronous orbit. The system can simultaneously monitor multiple targets in real time and obviously improve the time resolution of photographic observation, so that a real-time monitoring effect similar to a video is achieved; and furthermore, by optimal arrangement of remote sensing constellations, customization of multiple observation targets by a user, and motorized control of an attitude of a satellite covering all the targets, all-day video-similar real-time monitoring can be simultaneously performed on global multiple targets.

Description

technical field

[0001] The invention belongs to the field of satellite optical remote sensing, and relates to a global arbitrary multi-target all-time real-time monitoring system and method based on imaging in motion. Background technique

[0002] Space-based real-time monitoring. At present, only the geostationary orbit can realize all-day monitoring of fixed targets, and the orbit coverage and spatial resolution are limited. Due to the lack of agile maneuverability of existing remote sensing satellites, if a common sun-synchronous orbit is used to achieve a 10-minute revisit period for equatorial targets, at least 20 satellites are needed, and the time resolution of 10 minutes obviously does not meet the real-time monitoring requirements. In order to achieve global observation coverage and a temporal resolution of seconds, hundreds of satellites must be needed according to the traditional imaging mode, which will occupy a large amount of space resources and cause a large a...
