Xsens Sirius GNSS/INS Modules

Xsens Sirius GNSS/INS Modules are designed to maintain positioning accuracy and orientation stability where conventional GNSS/INS systems degrade. These modules combine a quad-band GNSS receiver with advanced sensor fusion to provide reliable, high-accuracy positioning and orientation. The Sirius GNSS/INS modules offer advanced sensor fusion for stable orientation and reduced drift. These next-generation GNSS/INS modules feature flexible interfaces, including RS232, RS422, CAN, and CAN-FD. The Sirius GNSS/INS modules provide uncertainty output for real-time data quality assessment and provide future-proof support for next-generation GNSS signals. These GNSS/INS modules are MIL-STD-202 tested for shock, vibration, and environmental robustness. Typical applications include autonomous ground vehicles, robotics, industrial automation, marine surface, subsea vehicles, offshore, marine heave compensation, surveying, and mapping systems.
