DSEI 2015: SAGEM Details Navigation System Deliveries

SAGEM’s Vice President Marketing & Sales Navigation, Fabrice Delhaye, spoke with MT about the contract awarded by the Royal Canadian Navy for the delivery of the Inertial Navigation Systems (INS) for the service’s six “Harry DeWolf” class Offshore Patrol Vessels (OPVs). He confirmed that each of these Arctic Offshore Patrol Vessels (AOPVs) will be equipped with two BlueNaute attitude and heading systems. The system is based on a proprietary technology, SAGEM’s Hemispherical Resonator Gyro (HRG), which was initially used for space applications. It can be operated in the harshest environments; so, it is ideally suited for long-duration missions in arctic zones. The system features Mean Time Between Failures (MTBF) exceeding 100,000 hours, according to SAGEM.
SAGEM already delivered the system for the US Coast Guard’s “Reliance” class medium-endurance cutters and “Juniper” class seagoing buoy tenders. Also, the company has won a competitive tender issued by the Royal Norwegian Navy to upgrade the navigation systems aboard its three “Nordkapp” class OPVs. The customer selected SAGEM’s SIGMA 40 laser gyro navigation system. According to the company, a decisive factor was the system’s long-term resistance to shocks.

The BlueNaute system offers a major improvement in terms of maintenance and total cost of ownership compared with previous generation navigation systems. (Photo: Stefan Nitschke)
