Abstract

The development of nanosatellites, which are generally defined by its weight ranging between 1kg-10kg, have grown considerably in the academia sector. The most popular form factor for spacecrafts in this category is the CubeSat form factor, as it opens up lower-cost launch opportunities and growing availability of commercial-off-the-shelf solutions for the spacecraft subsystems. For many nanosatellites orbiting in Low Earth Orbit, magnetic environment is an important aspect in its design consideration. This applies to both the platform engineering and mission design, as it influences the attitude system design as well as the design of the relevant scientific instruments. This thesis work contributes in the development of technology and techniques that can help in managing the influence of magnetic environment in spacecraft design, in particular the solution for magnetometers calibration and the detection of spacecraft residual magnetic dipole moment. The magnetometer calibration focuses on the implementation of rotational correction factor, which, in the more conventional techniques, is typically assumed to be in a certain condition. The detection of spacecraft residual magnetic dipole moment focuses on the early development of a machine-vision-assisted test bed that aims to reduce the mechanical and electrical complexity of the more common spacecraft automated magnetic test bed. Several missions, where the spacecraft has been developed and built in Aalto university, has been launched. From the perspective of practical performance of in-orbit spacecraft operation, this thesis work will also discuss the challenges and lessons learned from the operation of Aalto-1 attitude system. This thesis contribution is focused on the attitude analysis and sensors calibration of the Aalto-1 in-orbit operation.
