Abstract:

The U.S Air Force Defense Meteorological Satellite Program DMSP Block 5D satellite uses two general purpose digital flight computers for control of the satellite and launch vehicle. During the life of six satellites, various reconfigurations of the flight software were accomplished to achieve improvements or to compensate for problems. An independent verification and validation IVV process was conducted by CSDL on that flight software prior to launch and prior to uplink of major software changes. To accomplish this, CSDL developed and used a closed-loop digital simulation of the mission to exercise the actual flight software in a realistic environment. This paper describes this experience, focusing on how both the simulation and the IVV process evolved as a consequence of the flight history. Author
