Session
Technical Session XI: Advanced Subsystem or Component Developments I
Abstract
One of the broad objectives of the THNS-1 nanosatellite, which mass will be less 5kg, is to demonstrate the availability of micro/nano-technology. The attitude control system has a three-axis magnetometer, four two-axis sun sensors and a MIMU for providing an attitude knowledge. The extended Kalman filter will be used for determining the attitude angles and attitude velocity. Three reaction wheels will be used to perform off-nadir pointing manoeuvres with magnetorquers for momentum dumping. A gravity gradient boom with top mass, which was successfully used on many microsatellites in the world, will be used for passive nadir pointing stabilisation.
