ETRSS-1 attitude and orbit control subsystem and on-orbit 1 performance analysis

Abstract

The Ethiopian remote sensing microsatellite, weighing 65 kilograms, was successfully launched into space in December 2019 from the Taiyuan launch facility, with the mission of collecting earth imagery data to assist Ethiopia in combating climate change. The satellite is controlled from a sun-synchronous orbit at an altitude of 628 kilometers by a ground control station on Mount Entoto. The purpose of this paper is to provide an overview of the ETRSS-1 satellite system, including its development and integration with AOCS subsystems, as well as its performance in orbit. Furthermore, the hardware used in the development of the satellite’s AOCS will be discussed, and onboard telemetry data from the system will be analyzed to determine its current status.
