The present invention discloses a satellite communication method and system based on network coding and modulated-retro reflection. The method includes: constructing a satellite communication network based on modulated-retro reflection, and constructing, based on the satellite communication network, a plurality of preset basic structures for satellite communication in a preset network coding mode; performing structural splitting on the satellite communication network based on the plurality of preset basic structures to obtain at least one splitting mode including at least one basic satellite network structure, and acquiring, based on the preset network coding mode, a total transmission duration of satellite data transmission for all the preset basic structures in each first splitting mode; and determining a first splitting mode corresponding to a total transmission duration meeting a preset condition as a target splitting mode, and performing satellite data transmission by each preset basic structure corresponding to the target splitting mode.

Satellite communication method and system based on network coding and modulated-retro reflection

A modulated retro reflector-based satellite network communication system and method are provided. The system includes: a data acquisition layer configured to acquire data to be acquired, perform integrated analysis on the data to be acquired and send an integrated analysis result to a backbone network layer; the backbone network layer configured to receive a control instruction sent by a ground station, schedule first satellites based on the control instruction, and send the integrated analysis result to the ground station; and the ground station configured to generate the control instruction, send the control instruction to the backbone network layer, detect the first satellites and the second satellites, and receive the integrated analysis result. Through the system, the SWaP value of the satellite may be greatly reduced, thereby being suitable for communication networking of micro-satellites.
