Problems solved by technology

Due to the minimum number of satellites required and the simplest inter-satellite relay routing protocol, this design has been widely recognized for its low investment, but limited by the characteristics of satellite communication systems, satellites in geosynchronous orbit have Excessively high orbits have greater delays, and higher orbits also require greater launch costs. Therefore, this design cannot well support the rapid development of various communication services today, especially for delay requirements. For high-level services, how to improve the real-time data transmission capability of the separate modular satellite system under the premise of controlling costs has become an urgent problem to be solved

Abstract

The invention discloses a separation modular satellite system and a method based on MEO data relay. The system comprises a separation modular satellite cluster, an MEO data relay system and an earth station, wherein the separation modular satellite cluster generates data after onboard processing and sends the data to the MEO data relay system; the MEO data relay system performs routing on the data and sends the data to the earth station in a transparent forwarding mode; and the earth station performs further analysis processing on the received data to obtain a final result. According to the system and the method, end-to-end delay of the separation modular satellite system can be effectively reduced, and therefore real-time data transmission of the separation modular satellite system is achieved.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a system and method for real-time data transmission of separate modular satellites in the technical field of micro-satellites. Background technique [0002] Micro-satellite is a new concept satellite based on micro-electromechanical integration technology and special integrated micro-instruments composed of several micro-electro-mechanical systems. Its essence is a distributed satellite structure system. Several small satellites are deployed in different orbits in space in the form of distributed constellations as basic units, and they are connected to each other through telemetry and remote control to form a closely linked unified system to complete what a conventional satellite has. function. [0003] As a hot spot of today's aerospace technology, all countries have launched active research on micro-satellites, and the separate modular satellite system has beco...
