Test case generation for On Board Computer Software Major Components

PES Institute of Technology along with five other institutions is developing a student imaging satellite. In imaging satellite development, software implementation plays an important role. On Board Computer (OBC) is one which runs the satellite software. Satellite software has its sub components like telemetry, control modes, data processing, actuator, tele command and etc. Design, development and testing of these components are done successfully. Testing plays very important role to assure its software components functionality. In this paper, we present the testing methodology that we used along with main software components that we tested for on board computer. These test cases used to assure the functional correctness of control modes, actuator, tele command, telemetry and data processing of on board computer components.
