VectorNav Technologies’ VN-100 microelectromechanical systems (MEMS)-based inertial measurement unit/attitude and heading reference system (IMU/AHRS) has been integrated into Neya Systems’ custom version of its UxAB module.

The module will be integrated into Northrop Grumman’s Advanced Explosive Ordnance Disposal Robotic System (AEODRS) Increment 1 for the U.S. Navy. The VN-100 MEMS includes a 3-axis accelerometer, gyro and magnetometer and delivers a real-time 3-D orientation solution that is continuous over 360 degrees of motion at rates of up to 400 Hz.

The VN-100 includes VectorNav’s Vector Processing Engine (VPE), which is a suite of sensor fusion algorithms running on-board the sensor that deliver real-time magnetic and acceleration disturbance rejection, adaptive signal filtering, dynamic filter tuning and on-board Hard and Soft Iron compensation.

The VN-100 will be integrated directly into the electronics board of Naya’s UxAB platform, a fully self-contained semi-autonomy and autonomy capability module that includes GPS waypoint navigation, multi-joint manipulator control, retrotraverse, return-to-comms and optional obstacle avoidance behaviors.
