Lessons Learned – Mars Observer Inertial Reference Loss
Year: 1994
Abstract: Abstract:
Mars Observer experienced inertial reference loss on several occasions during its cruise to Mars. These incidents were due to the lack of a detailed code walk-through, and to use of gyro noise values, obtained from in-house test, that were more optimistic than the manufacturer's specifications. Do not depend on hardware performance being better than the manufacturer's specification. Perform detailed code walk-through of critical software modules. Pay special attention to inherited critical software. Design the flight computer and software to permit necessary changes in flight.
