VectorNav is a leading developer of state-of-the-art inertial navigation systems (INS) for unmanned systems.
Our tactical- and industrial-grade GNSS INS sensors provide unparalleled performance and capability for UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles), UUVs (unmanned underwater vehicles) and other robotic platforms.

Our MEMS inertial navigation systems deliver superior accuracy and reliability even under the most demanding and dynamic real-world conditions. Featuring robust performance in highly SWaP-optimized packages, our inertial systems are ideal for integration into cutting-edge and mission-critical technologies.


Our IMUs (inertial measurement units) deliver high-output rate, low-noise accelerometer, gyroscope and magnetometer data, fully calibrated across the full temperature range of -40 °C to +85 °C. All units incorporate an onboard AHRS (attitude, heading and reference system) algorithm for real-time, continuous 360° attitude (yaw, pitch and roll) output, providing optimal heading estimates even in challenging magnetic environments.
