Advanced Navigation introduces compact navigation system for military applications

Advanced Navigation has released the Boreas 50 series, marking the company’s smallest fiber-optic gyroscope (FOG) inertial navigation system (INS).

The new product line consists of two devices, the A50 attitude and heading reference system and the D50 strategic-grade INS. Both units feature north-seeking gyrocompasses designed to determine true north without relying on GPS signals or magnetic references.

The 50 series weighs 910 g and incorporates Advanced Navigation’s sensor fusion technology, which processes data from multiple sensors to maintain accuracy during GPS outages or interference. The system can detect Earth’s rotation to establish directional orientation within minutes of activation.

An optional Electronic Counter-Countermeasure capability is available for the D50, designed to detect and counter GPS jamming and spoofing attempts. The feature targets operations in contested electromagnetic environments where adversaries may attempt to disrupt satellite-based navigation.

“The modern battlefield is no longer defined by only physical boundaries, but by electromagnetic dominance,” said Maximilian Doemling, head of product at Advanced Navigation. “Assuming navigation will ‘just work’ is a mission-critical oversight.”

Performance Specifications

The system achieves heading accuracy of 0.5° secant latitude through gyrocompassing, with roll and pitch accuracy of 0.03°. Positional accuracy reaches 0.01 m circular error probable at 50% confidence level when GPS is available.

The devices meet military standards for shock and vibration testing, addressing requirements for platforms operating in harsh environments. The compact form factor enables integration into space and weight-constrained systems.

Defense applications for the 50 series span multiple domains. Military pointing platforms, including radar systems, can use the technology for target tracking and identification while mobile or stationary. The system’s rapid stabilization capabilities support accurate targeting despite motion and environmental interference.

Counter-unmanned aircraft system platforms benefit from the precise heading and stabilization features when tracking aerial threats. The north-seeking gyrocompass enables rapid target acquisition and tracking in dynamic operational environments.

Maritime vessels operating under GPS-denied conditions can maintain navigation capabilities and threat identification through the system’s independent positioning features. The technology aims to preserve tactical advantages when satellite signals are unavailable.

Intelligence, surveillance and reconnaissance platforms, along with unmanned aircraft systems, can address navigation failures and targeting errors caused by electronic warfare and sensor drift. The compact design accommodates both new and legacy aircraft integration requirements.

Ground vehicles, whether autonomous or crewed, gain protection against electronic interference that could compromise navigation and situational awareness. The anti-jamming and anti-spoofing capabilities maintain consistent positioning data during operations.

Advanced Navigation‘s defense division consists of military veterans who collaborate with system integrators, program offices and end-users to develop tailored solutions. The company plans to double its defense team size within the year.

The firm’s vertically integrated manufacturing approach aims to reduce production lead times compared to industry standards. Products carry a three-year warranty, and the 50 series provides a direct upgrade path for users of the company’s existing Spatial FOG Dual system.

The technology represents ongoing development in assured positioning, navigation and timing systems as military operations increasingly face electronic warfare threats targeting GPS-dependent systems.
