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

VN-300
The VN-300 is designed for applications that require highly accurate inertial navigation solution under both static and dynamic operating conditions, especially in environments with unreliable magnetic heading and good GNSS visibility. The VN-300 is the first and only Dual GNSS Antenna Inertial Navigation System in a single surface mount package. 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 MEMs sensors, GNSS receivers and electronics. Interfacing with the module is made through a locking 10-pin connector, as well as two MMCX connectors for external active GPS antennas.
