Advanced Navigation has announced the expansion of its Boreas range with the new 50 series – the company’s most compact fibre-optic gyroscope (FOG) inertial navigation system (INS). The 50 Series includes two high-performing devices: the A50, an attitude and heading reference system (AHRS); and the D50, a strategic-grade INS. Each is equipped with a North-seeking gyrocompass capable of rapidly determining true North. Powered by Advanced Navigation’s sophisticated sensor fusion, the series delivers intelligent, reliable navigation in the most demanding conditions – all within a compact, SWaP-optimised form factor.
The D50 is equipped with multi-band GNSS receivers, offering enhancements in signal availability, heading accuracy, and greater resilience in contested environments. For missions operating in particularly high-threat scenarios, it also offers an extra layer of protection through optional Electronic Counter-Countermeasure (ECCM) capabilities.
Maximilian Doemling, Head of Product at Advanced Navigation, said, “The modern battlefield is no longer defined by only physical boundaries, but by electromagnetic dominance. In this new reality, assuming navigation will ‘just work’ is a mission-critical oversight. The Boreas 50 Series goes beyond a traditional INS. In heavily contested zones, the D50’s advanced ECCM capabilities deliver uncompromising protection against nefarious attempts of GNSS jamming and spoofing. It is a powerful counter-EW solution built to operate under direct electronic attack, giving operators the resilience and reliability they need to stay on course against any adversary.”
Command Precision in Compact Form
- Real-time heading without GNSS: The 50 series contains precise North-seeking gyrocompassing, capable of detecting Earth’s rotation to determine true North in minutes, completely independent of GNSS signals or magnetic interference. This is housed in a compact form factor weighing 910 grams, enabling easy integration into space- and weight-constrained platforms.
- Continuous accuracy in dynamic conditions: Advanced Navigation’s proprietary sensor fusion draws on sophisticated algorithms to interpret and filter sensor data. The software is designed to dynamically weigh the input from each sensor, adjusting in real time based on reliability scores, environmental conditions, and operational context. This ensures continuous, high-confidence state estimation even when GNSS signals are lost, degraded, or distorted.
- Faster deployments, quicker decisions: The D50 incorporates dual-antenna, multi-band GNSS receivers, supporting up to four frequency bands. This design increases satellite visibility for faster signal acquisition and more stable, robust positioning in obstructed or interference-prone environments.
- “Zig” when the threat “Zags”: The D50 is available with optional ECCM functionality. While adversaries create GNSS signal attacks (“the ZAG”), the D50 proactively detects and neutralises these attacks to maintain a reliable, uninterrupted positioning (“the ZIG”).
Mission-Ready Across Contested Environments
The Boreas 50 series allows for seamless integration into defence platforms, reducing development time and minimising integration risk across both new and legacy systems.
- Military pointing platforms: Motion, shock, and environmental interference can compromise a stationary or mobile radar’s ability to track targets, leading to inaccurate identification. The 50 series is rigorously tested to military standards for shock and vibration. By using gyrocompassing to calculate heading and orientation within minutes, the series delivers the quick effective stabilisation required for radar platforms to maintain accurate target identification and tracking even on the move.
- Counter-UAS: Fast, responsive targeting is critical when tracking aerial threats. The 50 Series’ North-seeking gyrocompass delivers precise heading and rapid stabilisation, enabling counter-UAS platforms to acquire, aim, and track with speed and accuracy in dynamic environments.
- Maritime vehicles: The denial of GPS signals blinds a vessel’s precision capabilities, risking its ability to navigate effectively or accurately identify and track incoming threats. The 50 Series is engineered to endure GPS denial, navigate precisely, and deliver assets on target to maintain tactical advantage on the seas.
- ISR & UAS: EW and sensor drift lead to navigation failures and targeting errors, which is compounded by size and weight restrictions. The D50 with ECCM features delivers continuous and robust PNT, and overcomes the problem of sensor drift when combined with an external GNSS receiver or velocity aiding sensor. Further, its compact design supports seamless integration across both new and legacy UAS systems.
- Autonomous & tactical vehicles: Electronic interference can compromise vehicle navigation and situational awareness in the field. The D50 with ECCM features offers robust anti-jamming and anti-spoofing performance, delivering consistent, reliable heading and positioning data for uninterrupted autonomous or crewed operation.
