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...

AI Technical Summary

Problems solved by technology

[0005] The space-based platform and the ground station establish a single data transmission channel. When the ground station breaks down or is destroyed by humans during wartime, the space-based information will not be distributed to users, and there is a large single-point failure safety risk; the ground station first receives the space-based information. information, and then distributed to users, there are many links between information sources and users, the transmission link path is long, and the real-time performance of transmission is poor; , ground stations and ground networks are difficult to fully cover
