Sagem’s shipborne Sigma 40 inertial navigation systems exceed 5 million hours of operationThe Sigma 40 inertial navigation system by Sagem (Safran group) has passed the milestone of 5 million hours of operation in service. The data accumulated by this fleet clearly demonstrates the outstanding operational reliability of the naval Sigma
40, with MTBF (mean time between failure) of more than 35,000 hours. Operating data also shows that systems frequently exceed 50,000 hours in service without requiring any maintenance.
