Abstract

This MSc thesis has the objectives of simulating the behaviour of a typical COTS ADCS and designing a new attitude mode called Pitch Sun Tracking (PST). The Y-momentum ADCS is comprised of a set of sensors that are able to determine the attitude with an accuracy below 2 deg. The magnetorquers, aided by a momentum wheel, can keep the pointing error below 10 deg in Nadir Pointing (NP) mode. The PST mode proves to be capable of incrementing the power available to the satellite by more than 17%.
