The Boreas A50 from Advanced Navigation is an Inertial Navigation System designed to provide reliable attitude, heading and navigation in GPS-denied and harsh environments. It integrates fiber-optic gyroscopes and accelerometers, and the gyroscopes use a closed-loop optical coil with spread-spectrum modulation to accurately determine the heading (North-seeking), without requiring a GNSS or a magnetometer. This system provides a heading accuracy of 0.7° RMS at 45° latitude, a roll & pitch accuracy of 0.03° RMS, and a positioning accuracy of 0.01 m.
The gyroscope integrated into this inertial navigation system provides a null bias of 0.5°/hr and a range of ±490°/s, while the accelerometer provides a null bias of 30 mg and a range of ±10 g. This system is equipped with multiple interface options for control, including Ethernet and RS422, and also supports industry-standard protocols such as NMEA, 1PPS, and ANPP. It requires a DC supply of 9 to 36 V and draws 10 W of power. This system is available in a SWaP-C-optimized IP67 rated package measuring 94 x 94 x 85 mm. It is ideal for tactical vehicles, pointing platforms, maritime vehicles, drill dig alignment, ROV navigation, and fleet management applications.
