Abstract
The Ethiopian remote sensing microsatellite, weighing 65 kg, was successfully launched into sun-synchronous orbit at an altitude of 628 km in 2019. The satellite has a three-year lifespan and employs a maneuver that minimizes the orbit perigee without adjusting the orbit apogee, resulting in an eccentric disposal orbit, with the perigee altitude selected to ensure re-entry into the Earth’s atmosphere within 25 years. This study presents an overview of the ETRSS-1 satellite system, including its subsystems alongside the hardware utilized during their development, as well as an analysis of its on-orbit performance. Furthermore, the spacecraft’s electro-optical multispectral camera and its ability to capture remote sensing data while adhering to appropriate operational constraints, as well as its imaging mission techniques, various types of failure modes, and anomaly detection detection techniques, will be investigated.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
