This paper presents a model predictive control approach for regulating the attitude of magnetically actuated satellites. Unlike other contributions in this area, a predictive control approach is developed which guarantees closed-loop stability of satellite configurations with unstable open-loop pitch dynamics. With the pitch axis being unstable, two magnetic dipoles are used exclusively for reg...

SNAP-1 is a low-cost nanosatellite build by Surrey Satellite Technology Ltd. (SSTL), it is amongst other objectives a technology demonstrator for 3-axis stabilisation and orbit control for a future constellation of small satellites during formation flying. The satellite uses a single miniature Ymomentum wheel, 3-axis magnetorquer rods and a single butane gas thruster to ensure a nominal nadirpo...

Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far.&#10In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. &#10This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be ...

In attitude determination using GPS, the accuracy of results is influenced directly by the satellite selection of the differenced observations. Based on the information of satellites, such as elevation, azimuth and signal to noise ratio, we apply a weighted selection method to obtain the satellite combination used in attitude determination. This method also considered the quality of satellite s...
