The Xsens Sirius Dual-Antenna RTK GNSS/INS combines high-precision positioning and inertial sensing to deliver accurate navigation and true heading for unmanned platforms.
Xsens showcases its Sirius Dual-Antenna RTK GNSS/INS, a rugged navigation system designed to provide precise positioning, orientation and heading without relying on magnetic measurements or platform movement.
Integrating dual GNSS antennas with advanced inertial sensor fusion, the system delivers centimeter-level RTK positioning and true north-referenced heading, including when operating at standstill or low speeds. Heading accuracy reaches 0.05° RMS with a 2 m antenna baseline, while roll and pitch accuracy is 0.2° RMS.
Housed in an IP68-rated aluminum enclosure, Sirius also provides real-time heave measurements for marine applications and supports integration through CAN, CAN-FD, RS232 and RS422 interfaces. The system is suited to USVs and other unmanned platforms operating in demanding environments.
