Session 10: Year In Review
Abstract
A satellite’s Power Subsystem is in charge of delivering power to the rest of the satellite subsystems during the different phases of the mission. This critical subsystem can be modeled as a three-component system: a primary energy source, a secondary energy source that will be used whenever the primary source is not available or sufficient and third, the loads of the subsystem, which represents the rest of the satellite power requirements. In this paper, the process for modelling, simulating and sizing these three components is presented as well as the results of applying this methodology on two real commercial earth observation satellites called NewSat-1 and NewSat-2. Finally, in-orbit telemetry is presented and used to verify the subsystem functionality.
