Xsens has introduced the Dual Antenna RTK GNSS/INS, a navigation solution designed to deliver precise position, orientation, true heading, and heave from startup, including when a platform is stationary or moving at low speed.
Conventional single-antenna and magnetometer-based navigation systems can require a platform to move before heading is available, or can be disturbed by nearby metal, motors, and electrical systems. The new Dual Antenna sensor module combines Xsens sensor fusion technology with a u-blox ZED-X20D all-band high-precision GNSS receiver. This configuration provides centimeter-level positioning and motion-independent heading, making it particularly suited for machinery, robots, vessels, and stabilized platforms operating from a standstill or at low speeds.
The hardware is offered in two distinct form factors to accommodate different integration requirements. The Avior Dual Antenna variant is designed as a compact, lightweight module for original equipment manufacturers seeking embedded integration and can be integrated with a wide range of external GNSS receivers. For exposed outdoor installations, the Sirius Dual Antenna variant packages the same core navigation capability in an IP68-rated aluminum housing tested according to MIL-STD-202 for shock, vibration, and environmental robustness. Operating across a temperature range of -40°C to +85°C, the Sirius system supports RS232, RS422, CAN, and CAN-FD interfaces.
The release builds on an established collaboration between Xsens and u-blox, whose positioning technology is already used across other parts of the Xsens inertial sensor portfolio.
Martijn van den Linden, Product Manager at Xsens, commented, “This is an important addition to the Xsens portfolio. By combining Dual Antenna GNSS with our advanced sensor fusion, we can deliver even greater heading accuracy and centimeter-level positioning to applications that need dependable navigation data from startup. We see a particularly strong fit in slow-moving and stationary applications, where knowing both position and direction without waiting for motion can make integration and operation significantly faster and more reliable.”
JunJun Lu, Principal Product Manager at u-blox, added, “At u-blox, we know that strong technology partnerships are essential to turn high-precision positioning into successful customer solutions. Xsens is a trusted, long-standing partner with whom we already collaborate across other parts of its sensor portfolio. By integrating reliable and out-of-the-box ZED-X20D all-band heading solution, we are combining complementary expertise to help our shared customers shorten development time, deploy with confidence, and maximize the success of their applications.”
The Xsens Dual Antenna RTK GNSS/INS is scheduled for introduction in September 2026 and will be presented at INTERGEO 2026, with orders and availability to follow.
