FOG inertial navigation system Boreas 50

lightweightminiaturewith integrated dual-antenna GPS

Overview
The Boreas 50 Series is a compact inertial navigation system providing north‑seeking gyrocompass capability and reliable navigation in GNSS‑denied and harsh environments.

Key performance metrics
Horizontal Position Accuracy (GNSS RTK): A50 — 0.01 m (CEP50); D50‑X20P / D50‑MX5 — 0.01 m (CEP50).
Roll & Pitch Accuracy: 0.03 ° (RMS).
Heading Accuracy (Gyrocompass): 0.5 ° × sec(lat), 1σ (≈ 0.7 ° RMS at 45° latitude).

Features

• North‑seeking gyrocompassing (FOG) for accurate heading and orientation without GNSS or magnetometer.
• FOG (Fiber Optic Gyroscope) closed‑loop optical coil and spread‑spectrum digital modulation for improved accuracy, stability and reduced SWaP‑C.
• Industry‑leading SWaP‑C — compact, lightweight precision enclosure suitable for constrained platforms.
• Aluminium enclosure rated IP67; designed and tested to MIL‑STD‑461 (EMC) and MIL‑STD‑810H (environmental).
• Multi‑protocol support and multiple physical interfaces; embedded web interface and up to one year internal data logging.

Boreas 50 series variants

• A50 — provides heading and orientation as an AHRS and INS.
• D50‑X20P — dual‑antenna all‑band GNSS receiver (dual antenna heading capability available on X20P from July 2026).
• D50‑MX5 — dual‑antenna multi‑band GNSS receiver with electronic protection (resilience against jamming and spoofing).

Applications

• Tactical vehicles
• Pointing platforms
• Maritime vehicles
• Drill rig alignment
• Fleet management
• ROV navigation
