Tactical Series

Tactical-Grade IMU/AHRS, GNSS/INS & Dual Antenna GNSS/INS

Tactical Series MEMS Inertial Navigation SolutionsThe Tactical Series range of high-performance, MEMS-based, inertial navigation systems features IMU, AHRS, GPS/INS and GPS-Compass solutions designed for a wide range of demanding applications and operating environments.

Encased in a ruggedized aluminum housing, the Tactical Series is built around a compact tactical-grade MEMS IMU core. Our industry leading algorithms provide high-accuracy position, velocity, and attitude estimates along with compensated inertial measurements at rates up to 800 Hz.

Each unit undergoes an extensive individual sensor calibration across the full operating temperature range (-40°C to +85°C) for bias, scale factor, misalignment, temperature dependancies and gyro g-sensitivity.

Applications of our Inertial Navigation Systems

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.

Read how Ghost Robotics uses VN-100 IMU/AHRS to provide accurate attitude data for its ground robot.

GPS/INS for UAV Control & Navigation

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.

Read how the Hydra S45 medium-range UAV uses VN-200 GPS/INS for primary navigation.

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.
