Space-based information distribution system and distribution method

Abstract

The invention discloses a space-based information distribution system and method. The system comprises a mobile transceiving terminal and a space-based distribution terminal; the mobile transceiving terminal comprises a track calculation module, a task generation module and a wireless transceiving module; the space-based distribution terminal comprises a space-based receiving module, a comprehensive processing module and a space-based transmitting module; the mobile transceiving terminal is installed on a user; the space-based distribution terminal is installed on a space-based platform; and the mobile transceiving terminal and the space-based distribution terminal are connected in a wireless connection mode, and perform information communication. The space-based information distribution system and method can directly distribute space-based information of the space-based platform to the user, so that the transfer link of a ground station is omitted, the problem that the user cannot receive the space-based information due to the fact that the ground station is damaged can be avoided, and relatively high timeliness and security are achieved; and information distribution for users inall visual ranges can be realized, so that the problem that remote areas and mobile users cannot receive the space-based information is solved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space-based information distribution system and a distribution method. Background technique [0002] The space-based information network is a comprehensive aerospace information system composed of a variety of spacecraft, satellite networks or satellite constellations with different functions, including multiple payloads such as remote sensors, locators, and transponders, as well as space-based platforms. Existing space-based platforms cover a wide range. Space-based platforms are equipped with earth observation payloads such as optical imaging, microwave imaging, signal reconnaissance, and synthetic aperture radar (Synthetic Aperture Radar, SAR), which can achieve rapid wide-area information acquisition. And it is not restricted by land, territorial sea and national boundaries. The data obtained can not only provide information services and decision support for important fi...
