The goal of this report is to summarize the ideas, designs, methodologies and data of
this final year project. This final year project report gives a fundamental
understanding of the attitude control system of a Cube Satellite (CubeSat) and the
detailed explanation of the various experimentations conducted on the selections and
sizing of the hardware components. The type of attitude control system chosen for
this satellite project is passive magnetic attitude control system which is a pure
passive control system ideal for nanosatellites such as CubeSats. This attitude
control system is designed for VELOX-LYON-1 3U CubeSat from Satellite
Research Centre at Nanyang Technological University.
Passive Magnetic Attitude Control system (PMAC) mainly consists of bar magnets
and hysteresis rods. In this report, characterizations of the permanent bar magnets
and hysteresis rods are performed experimentally. Bar magnets with 3 different
dipole moments were characterized. The hysteresis rod material chosen is HyMu-80
Permalloy. Various experiments are conducted with the goal of evaluation the actual
magnetic behaviours of both the magnets and the hysteresis rods. As for the bar
magnets, actual dipole moments should be examined while for hysteresis rods, its
magnetic parameters such as remanence, coercivity and saturation have to be studied.
Before the sizing and selections of the hardware, basic aerodynamic theories were
being introduced and discussed as the space environmental torques are seen as a
form of disturbances to the CubeSat which will affect the attitude determination and
control. Space environmental torques are computed and the sizing of the bar magnets
depends on the calculated values.
The data collected has been further processed and analysed. The results of the
experiments are also been discussed in-depth. |
