Abstract
The VIrtual Super Optics Reconfigurable Swarm (VISORS) mission is a distributed space telescope consisting of two
6U CubeSats that utilize precision formation flying to detect and study the fundamental energy release regions of the
solar corona. The inherent complexities and risks associated with two spacecraft operating in close proximity, as well
as the unique restrictions of the spacecrafts’ design, make careful autonomous execution crucial to the success of the
mission. To address these challenges, this paper outlines the development of the Hosted Software Application (HSA)
flight software which manages the Guidance, Navigation, and Control (GNC) algorithms, the payload finite state
machine, and the spacecraft and formation level fault management system. An overview of the HSA provides context
for the motivation and requirements driving the design of the flight software system. The architecture of the HSA is
presented and shown to be derived from the Mission Events Timeline (MET) for each of the relevant phases of the
mission. Finally, this paper briefly discusses the software's implementation and test campaign.
