Advanced Navigation has addressed the critical operational risks posed by sophisticated electromagnetic warfare through the integration of multi-layered electronic protection in naval architectures.
The integrity of naval navigation has become a primary concern as jamming and spoofing technologies become more accessible to various adversaries. These threats go beyond simple signal loss, often introducing subtle data corruption that propagates through a vessel’s Combat Management System. Such interference has resulted in tactical latency, where operators must manually verify positioning data, and degraded engagement capabilities for weapon systems that rely on precise attitude and heading data. In highly contested environments, this loss of data integrity has led to operational paralysis when commanders cannot trust their own-ship position.
To mitigate these risks, the company has focused on the integrity of the sensor fusion engine rather than solely hardening GPS receivers. By utilizing accelerometers, gyroscopes, and filtering algorithms, these systems create an internal “truth” that remains resilient against external interference. This architecture has enabled integrity monitoring that detects spoofing characteristics, such as unrealistic velocity gating, allowing the system to transition to inertial-only navigation without data discontinuities.
Scalable Navigation Solutions
The company has developed a range of hardware to suit different vessel requirements, from uncrewed systems to strategic surface combatants. These products have been designed as ITAR-free to reduce administrative friction and enable rapid deployment for allied fleets.
For uncrewed surface vessels (USVs) operating in intense littoral zones, the Certus Evo has been introduced. This system utilizes MEMS (Micro-Electro-Mechanical Systems) technology to provide high-performance navigation in a compact form factor with a low SWaP-C profile. An electronic protection variant of the Certus Evo is also available, featuring a multi-band receiver for enhanced resilience against jamming.
Precision for Underwater and Surface Combatants
For platforms requiring absolute integrity, such as uncrewed underwater vehicles (UUVs) and crewed surface vessels, the Boreas D Series has been deployed. The Boreas D50, D70, and D90 utilize Fiber Optic Gyroscope (FOG) technology to offer best-in-class free inertial and dead reckoning performance during total GPS denial. The Boreas D50 specifically features fast north seeking capability, ensuring that heading instability does not consume the dead-reckoning error budget during extended submerged operations.
As electromagnetic threats continue to evolve, the integration of these inertial technologies ensures that naval navigation remains true even when external satellite data is compromised.
