Active Permanent Magnet Attitude Control For Cubesats Using Mu-Metal Shielding, Maxwell Martin
Active Permanent Magnet Attitude Control For Cubesats Using Mu-Metal Shielding, Maxwell Martin
Mechanical Engineering Undergraduate Honors Theses
Cube-Satellites (CubeSats) are nanosatellites composed of cube shaped units, each nominally 10cm to a side and around 1kg in mass. Due to their inherent size and weight limitations, it is often impractical to use conventional attitude, or rotational, control methods such as thrusters on these small satellites. Several methods, including magnetorquer rods and small reaction wheels, are often used instead of traditional methods to work around the size and weight limitations. As a new alternative to these methods, a permanent magnet mounted on a rotatable shaft could be used to achieve attitude control. In much the same way that a …

A Solid State Nitrogen Gas Generating Chip And Applications For Picosatellites, Kyle Godin
Graduate Theses and Dissertations
A microscale gas generating chip has many applications; in this study, applications relating to picosatellites have been considered. Cube satellites, a type of picosatellite, are of mass around one kilogram and side length 10cm x 10cm x 10cm. Their launches are becoming more numerous since their debut ten years ago. Their low cost and deployment system makes space accessible to agencies hitherto barred from it, such as universities and small governments. However, their power, mass, and volume budget is extremely tight. A microscale gas chip could compete with other designs for attitude control devices, most not flown yet as cube …
