An Autonomous Request Orbit Service System for Microsatellites

Abstract

A micro-satellite independent request orbit service system, which includes a ground measurement and control system, on-board management and control application software, and satellite-ground data interaction interface; the ground measurement and control system, including a measurement and control center and a measurement and control station, is used for remote control command injection and telemetry data reception processing and precise orbit determination; the spaceborne management and control application software includes an autonomous orbit determination module, a high-precision orbit forecast module, and a task scheduling management module; the satellite-ground data interaction interface is used to realize the format agreement of the satellite-ground uplink data and downlink data. The purpose of the present invention is to provide a micro-satellite autonomous control technology that can maintain orbit prediction results equivalent to the accuracy of orbit calculations on the ground on the satellite, so as to solve the problem that the existing technology can only meet the requirements of satellites in general micro-satellite orbit prediction tasks. The medium precision requirements of the position are difficult to meet the technical problems of high precision requirements for satellite payload applications such as autonomous mission planning.
