MicroStrain by HBK is a leading developer of innovative positioning and navigation solutions for challenging military and defense applications. Our MicroStrain line of tactical inertial sensors provides unmatched performance even under the most unpredictable and difficult operating conditions.
The state-of-the-art MicroStrain inertial sensing systems have been integrated into a wide variety of manned, unmanned and autonomous vehicles and platforms, serving armed forces on land, at sea and in the air.
High Performance IMUs, VRUs & Tilt Sensors
We provide a range of high-performance and tactical-grade inertial sensors, using state-of-the-art MEMS three-axis gyros, inclinometers and accelerometers to measure a variety of critical parameters including orientation, linear acceleration and angular rate.
Our low-SWaP inertial measurement units, vertical reference units and inclination sensors are fully calibrated and temperature-compensated and utilize sophisticated Kalman filtering for the utmost in reliability. Military applications include antenna and platform control, alignment and stabilization, auto-steering and precision navigation for drones and robotics.
Attitude & Heading Reference Systems
In addition to IMU outputs such as acceleration and angular rate, our military Attitude and Heading Reference Systems provide a variety of computed outputs including highly accurate attitude and heading estimates. Featuring three axes of precision accelerometers, gyroscopes, and magnetometers, the military AHRS sensors are ideal for antenna and platform stabilization and mobile robotics applications.
All sensors are fully calibrated, temperature compensated, and include our sophisticated proprietary Auto-Adaptive Extended Kalman Filtering capabilities for reliable performance even in challenging dynamic conditions.
Tactical GNSS-Aided Inertial Navigation Systems
Our high-performance and tactical-grade GNSS-aided INS solutions combine low-noise and low-drift inertial sensors with integrated multi-constellation GNSS receivers to deliver accurate estimates of position and orientation even during satellite signal outages. Providing pitch, roll, yaw, heading, position, velocity, and GNSS outputs, the sensors are ideal for precision tactical navigation and autonomous robotics applications.
The compact and lightweight sensors are fully calibrated, temperature-compensated, and mathematically-aligned to an orthogonal coordinate system. Advanced tightly-coupled extended Kalman filtering (EKF) delivers state-of-the-art sensor fusion for superior accuracy even under extreme conditions.
RTK Network Modem
Our RTK network interface modem provides RTK correction data that can be used to enhance the positioning performance of our GNSS-INS systems to centimeter-level accuracy. It utilizes a cellular connection to communicate with our SensorCloud RTK network, doing away with the need for local base station infrastructure.
The easy-to-use RTK corrections modem is ideal for providing precision positioning and navigation for autonomous vehicles and robotics platforms, and for enabling BVLOS operations.
