GNSS-Aided INS with Integrated GNSS-Compass


The VN-300 is a miniature, high-performance Dual Antenna GNSS-Aided Inertial Navigation System (Dual GNSS/INS) that combines MEMS inertial sensors, two high-sensitivity GNSS receivers, and advanced Kalman filtering algorithms to provide optimal estimates of position, velocity, and attitude. The onboard GNSS-Compass enables accurate heading measurements without reliance on vehicle dynamics or magnetic sensors, providing unmatched performance under both static and dynamic conditions.

The VN-300 is the first and only Dual GNSS/INS in a single surface mount package (SMD). At the size of a postage stamp, the VN-300 SMD requires only a single 3.2-5.5V power supply and can be directly embedded into a user’s electronics for unprecedented SWAP advantages. The VN-300 Rugged is the “plug and play” version of the VN-300 SMD. Enclosed in a clamshell precision anodized aluminum enclosure, the VN-300 Rugged offers additional protection of the internal inertial sensors, GNSS receivers and electronics.

Each individual VN-300 sensor undergoes a robust calibration and acceptance testing process at VectorNav's AS9100 certified manufacturing facility.

VectorNav regularly conducts comprehensive testing on all products to verify continued conformance to all performance specifications.
