VectorNav is a leading developer of embedded inertial navigation solutions designed for integration into cutting-edge and mission-critical technologies.
VectorNav’s SWaP-C optimized tactical- and industrial-grade GNSS Inertial Navigation Systems (INS) sensors provide high performance and capability for unmanned systems operating in defense, military, aerospace, and marine industries worldwide.
We develop Inertial Measurement Units that deliver high-output rate, low-noise accelerometer, gyroscope and magnetometer data, and are fully calibrated across the full temperature range of -40 °C to +85 °C.
All our units incorporate an onboard Attitude, Heading and Reference System (AHRS) algorithm for real-time, continuous 360° attitude (yaw, pitch and roll) output, providing optimal heading estimates even in challenging magnetic environments.
Our GNSS-aided INS, featuring industry-leading inertial navigation algorithms, deliver higher-accuracy estimates and better dynamic performance than standalone GNSS or INS.
Outputting accelerometer, gyroscope and magnetometer data, as well as attitude, position, velocity and timing, our GNSS/INS go beyond what products of their size and weight typically deliver.
Inertial Navigation Primer
We’ve authored a comprehensive educational introduction to the principles of inertial navigation. Our Inertial Navigation Primer includes coverage of:
- Theory of Operation (GNSS, MEMS Sensors, AHRS, GNSS/INS)
- Math Fundamentals (Reference Frames, Attitude, Filtering, Feedback)
- Specifications & Error Budgets (IMU Specifications & Calibration, INS Error Budget, GNSS Error Budget)
- Hardware (Asynchronous & Synchronous Serial, RF, EMI)
