OXTS Inertial+2 GPS Inertial/GNSS Navigation System

Product Description

Oxford Technical OXTS Inertial+2 GPS Inertial/GNSS Measurement Navigation System

The Inertial+ is an add-on for GNSS receivers to improve reliability and accuracy. The Inertial+ uses accelerometers and angular rate sensors (gyros) to smooth the jumps in GNSS and fill in missing data. Other important measurements, such as heading, pitch and roll, can also be measured.

Clean and in excellent condition. These were removed from a prominent DOE facility during upgrade. GPS, IMU sensors and PC connection (NAVsuite configuration utility) tested onsite without issue.

Comes as shown with main unit, 2x antennas w/ cables, case and 12v connector. We can wire the connection for either the included 12V car adapter or a 120v AC power supply.

This innovative approach gives the Inertial+ several distinct advantages over systems that use GNSS alone:

• All outputs remain available continuously during GNSS blackouts when, for example, the vehicle drives under a bridge.
• The Inertial+ recognises jumps in the GNSS position and ignores them.
• The position and velocity measurements that the GNSS makes are smoothed to reduce the high-frequency noise.
• The Inertial+ makes many measurements that GNSS cannot make, for example acceleration, angular rate, heading, pitch, roll, etc.
• The Inertial+ takes inputs from a wheel speed odometer in order to improve the drift rate when no GNSS is available.
• The Inertial+ has a high (100 or 250 Hz) update rate and a wide bandwidth.
• The outputs are available with very low, 3.5 ms latency.
