Inertial navigation
for navies
At the heart of a vessel's navigation is the Inertial Navigation System (INS) or Attitude Heading and Reference System (AHRS), delivering essential navigation and position data independent of GNSS signals. Exail, a European leader in naval navigation, provides over 50 navies worldwide with high-performance, maintenance-free INS solutions. Our systems are designed for all types of naval platforms, from small vessels to aircraft carriers and submarines, offering reliable coverage without ITAR restrictions.
Powering operational superiority
Superior navigation performance
Designed to meet the demands of modern naval operations, Exail systems provide the tactical edge needed to execute with confidence in any scenario. Powered by Fiber Optic Technology (FOG), Exail’s AHRS and INS systems are purpose-built for high-stakes naval missions, ensuring precise navigation when it matters most.
- Mission-critical accuracy : drift as low as 1 NM per 360 hours for reliable positioning in extended operations
- Dynamic adaptability : real-time navigation in rapidly changing maritime condition
Resilient navigation in GNSS-denied environments
Exail navigation systems ensure uninterrupted performance in GNSS-denied environments, maintaining resilience against jamming and spoofing. Critical for naval forces in high-threat zones or during electronic warfare, they provide reliable navigation without satellite reliance, preserving mission integrity even in contested or disrupted conditions.
Enhanced stealth capabilities
Exail’s solid-state systems are designed to minimize acoustic signatures, ensuring silent navigation during covert operations. With low acoustic emissions, they enable submarines to operate undetected, providing critical advantages for stealth missions and enhancing security in high-threat environments. This allows naval forces to carry out sensitive operations with maximum discretion and operational effectiveness.
Robust design for operational continuity
Exail systems are engineered for long-term performance, ensuring maximum operational efficiency for naval fleets while reducing total cost of ownership.
- No mechanical moving parts: minimizes maintenance requirements.
- Lower lifecycle costs: reduces upkeep and associated expenses.
- Long-term reliability: ensures mission readiness with less downtime.
