Exail has launched a new inertial navigation system designed to maintain positioning and navigation continuity during amphibious operations, where forces move from sea to land in environments that may be affected by GNSS disruption.
The company said the system, called Advans Vega SL, is intended to operate independently of external signals from vessel departure to shore, aiming to support continuous positioning and fire-control readiness without reconfiguration during the transition.
In contested littoral environments, GNSS jamming, spoofing or signal unavailability can affect navigation systems that rely on satellite inputs. Exail said the Advans Vega SL is designed to address this by providing a single, self-contained solution for both maritime and land phases, avoiding the reconfiguration and handover challenges associated with multi-system architectures.
“GNSS signal denial is now an operational assumption in any amphibious and littoral combat planning. The Advans Vega SL removes satellite dependency at the most exposed phase of an amphibious operation, giving forces the autonomy to project ashore on their own terms,” said Yann Le Balc’h, Business Development Manager for Land Defense at Exail.
Exail said the system is based on its fiber optic gyroscope technology and provides 0.05° RMS heading accuracy during the maritime phase and 0.5 mils RMS on land.
