Abstract

The successful operation of any Earth observation satellite hinges critically on the precise performance of its Attitude and Orbital Control System (AOCS). This article details the in-orbit validation and performance analysis of the AOCS onboard the First Ethiopian Remote Sensing Satellite (ETRSS-1) [15]. ETRSS-1, designed for Earth observation, relies on a robust AOCS to achieve its mission objectives, which include image acquisition, data transmission, and maintaining orbital stability. This paper outlines the system's architecture, key components, and the methodologies employed for on-orbit commissioning and performance assessment. Initial flight results demonstrate the AOCS's ability to maintain the satellite's attitude within specified limits and to execute orbital maneuvers effectively, thereby validating its design and implementation for supporting various remote sensing applications.
