As part of this initiative, NCTS has worked with Surrey Satellite Technologies Limited (SSTL) to develop a 100 kg class enhanced microsatellite, Alsat-1. With the successful completion of this project, NCTS will be capable of designing its own satellites, covering all phases from design to production and in orbit operation. Alsat-1 was successfully launched from Plesetsk Cosmodrom in Russia in 28 November 2002. In this study the attitude determination and control system in orbit result of Alsat-1 is presented.} }
