AHRS/IMU for Ground Based Robotics

Unmanned Ground RobotGround based robotic vehicles operate in a wide range of environments where magnetic interference often makes heading determination difficult. The VN-100 range utilizes proprietary adaptive filtering and disturbance rejection algorithms which provide more accurate and stable heading measurements when magnetic interference is present. Vibration from nearby electric motors can be eliminated utilizing the on-board adaptive filtering capabilities provided by the Vector Processing Engine algorithm.

AHRS/IMU for Unmanned Underwater Vehicles UUV

Unmanned Underwater VehicleThe VN-100 range is well suited for underwater vehicle applications where precise heading, pitch and roll measurements are required. The sensor is capable of operation in any orientation and is not hostage to problems associated with gimbal lock. VN-100 is the only Attitude Heading Reference Sensor in its class to offer on-board hard & soft iron calibration capabilities This allows the sensor to compensate for magnetic distortion from nearby electric motors and batteries while in the field.

GPS/INS for Unmanned Aerial Vehicles

Unmanned Aerial VehicleThe VN-200 provides exceptional performance for autonomous control of unmanned aerial platforms. With an update rate of 200 Hz, high bandwidth, low-latency position and attitude measurements can be directly connected to the necessary control loops. The VN-200 calibration procedures ensure a high accuracy pitch and roll solution relative to the horizon while the on-board barometric pressure sensors provide autonomous aircraft with greater ability to precisely hold altitude.

GPS/INS for Camera Stabilization

The high pointing accuracy and low latency of the VN-200 makes it well suited for airborne camera stabilization applications. Utilizing the GPS and pressure sensor measurements together with the inertial sensor measurements, the onboard INS algorithm estimates absolute heading to better than 1 degree in yaw, pitch and roll in dynamic environments.

GPS/INS for Marine Antenna Stabilization

Marine Antenna StabilizationMaritime VSAT satellite communications require stabilized antennas that remain pointed at the satellite in order to ensure continuous data transmittal. Regulations require that pointing accuracies remain better than 0.5 degrees to maintain active transmission. This requirement demands highly accurate, precise and low latency attitude and angular rate measurements.

The dynamic motion common to rough sea conditions makes this a difficult task for most industrial grade MEMS-based inertial navigation systems. The VN-200 GPS assisted inertial navigation algorithm is capable of compensating for dynamic acceleration induced from the motion of the vessel while maintaining accurate orientation measurements. With a full filter state update rate of 200 Hz, the VN-200 provides extremely low latency attitude and angular rate measurements, critical for closed-loop control.
