FORESAIL-1 and FORESAIL-2 are the first two small satellite missions under development by the Finnish Center of Excellence Research in Sustainable Space (FORESAIL) and will be launched to LEO and GTO, respectively. Mission requirements become more stringent with each consequent satellite, as the space environment becomes harsher with higher orbits and scientific/technological payloads increase in complexity and require more power to operate. Both satellites feature an Electrical Power System (EPS), entirely developed at Aalto University, Finland. The design goal has been to develop a system which can be easily adapted to changing mission requirements and allow flexibility in supply rail configuration for avionics subsystems and payloads. Testing and verification campaigns play a critical role in validating performance and reliability of the EPS.
