The OxTS GNSS and inertial systems are advanced high-precision instruments for measuring motion, position and orientation of land vehicles, naval vehicles or aircrafts including UAVs. All products contain a six-axis inertial measurement unit and incorporate a multi-constellation GNSS receiver. Inertial navigation systems combined with GNSS provide highly accurate measurements of position, acceleration, velocity, true heading, roll, pitch, yaw, etc. in real-time. They’re also integrated with a variety of correction methods such as SBAS, DGPS, and RTK.
