Oxford Technical Solutions (OxTS) has rolled out its Inertial+, an inertial navigation system that can be used with an existing GPS receiver to improve position measurements, according to the company.
The Inertial+ includes inertial sensors, processing engine, and algorithms. It is built around a 6-axis inertial measurement unit — including three angular rate sensors (gyros) and three servo-grade accelerometers — to measure position and velocity even when GPS is not available, OxTS said.
Designed for surveying in an urban environment, the Inertial+ is able to ignore or correct jumps in the GPS measurements. In addition to position data when combined with a GPS receiver, the device will also produce measurements like roll, pitch, and heading. Data is read and output in NMEA format, and other formats are supported. By combining an Inertial+ with a high-accuracy real-time kinematic (RTK) GPS receiver, users can achieve 1 centimeter precision, 0.03 degrees roll/pitch accuracy, and low drift rates when GPS is not available, according to the company.
