1. Inverse source modeling of roll induced magnetic signature
University essay from Uppsala universitet/Avdelningen för beräkningsvetenskapAbstract : Vessels constructed in electrically conductive materials give rise to frequency-dependent, induced magnetic fields when waves of water cause them to roll in the Earth's magnetic field. These fields, typically referred to as roll-induced magnetic vortex fields, are a component of the ship's overall signature, where signature refers to measurable quantities which can reveal or identify objects.

2. Magnetic Moment Characterization for Small Satellites
University essay from Luleå tekniska universitet/RymdteknikAbstract : Small satellites are gaining popularity in a wide range of applications where attitude systems require high precision performance. One of the main sources of errors, in case of magnetic attitude control systems, is the residual magnetic moment (RMM) of the spacecraft. READ MORE

3. Test bench for Nanosatellite Attitude Determination and Control System (ADCS)devices : Design and manufacture of a Merritt Cage
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Attitude Determination and Control System (ADCS) is often a complex system on-board any satellite which needs validation and testing to prove its operability and verify its software compatibility with hardware and other subsystems. One failure in orbit is extremely expensive in terms of cost and time due to payload preparation and launch. READ MORE
