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.
