The purpose of this paper is to present about the designand methodology of DubaiSat-2 Flight Software. Thedesign of the flight software consists of tasks thathandle the satellite’s different operations. These taskscommunicate using internal communication protocols.The flight software communicates with the subsystemsof the satellite and the ground station using externalcommunication protocols. In addition, the flightsoftware includes some safe-hold modes that handlethe satellite in case any critical faults occurred. Finally,the development and testing environment are presentedin this paper.
