In contested littoral environments, maintaining reliable navigation across the sea-to-land transition remains a persistent challenge for amphibious forces. In the event of Global Navigation Satellite System (GNSS) jamming, spoofing, or signal unavailability, the Advans Vega SL operates independently of any external signal from vessel departure to shore, ensuring forces maintain continuous positioning and fire control readiness without reconfiguration at any stage.

As a single, self-contained solution covering both maritime and land phases, it also removes the integration constraints associated with multi-system architectures, which typically require reconfiguration or handover at the water-to-land transition.

“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.

Drawing on Exail’s Fiber Optic Gyroscope technology, the Advans Vega SL delivers 0.05° RMS heading accuracy in the maritime phase and 0.5 mils RMS on land—the highest navigation precision achieved to date in a system designed for the full sea-to-land transition. This performance level is rooted in decades of navigation expertise across land and naval operations, now brought to bear on a capability requirement that has become increasingly critical in modern amphibious warfare. With navigation systems in service with more than 70 navies and land forces worldwide, Exail is a recognized supplier for defense forces requiring sovereign, signal-independent positioning capability across all operational domains.
