Design and Verification of Control System for Terrestrial Ecosystem Carbon Inventory Satellite
摘要
The attitude and orbit control system of Terrestrial Ecosystem Carbon Inventory satellite proposes performance requirements of high attitude determination accuracy, high pointing accuracy and high stability. It also proposes geographic information service function, rapid inertial scanning function based on momentum wheel control and high temperature ground-target recognition and real-time prediction function. The purpose of geographic information service function is to coordinate with overall autonomous task planning. This article mainly introduces the design of geographic information service, rapid inertial scanning and high temperature ground-target recognition and real-time prediction function. Based on the satellite’s in orbit operation data, the in orbit verification of the control subsystem’s single machine and system performance indicators was provided.
