/ VN-300

The VN-300 is a compact, high-performance dual-antenna GNSS assistance that combines MEMS inertial sensors, two highly sensitive GNSS receivers, and advanced Kalman filtering algorithms to provide the best possible estimates of position, velocity, and orientation. It is an inertial navigation system. By utilizing two separate GNSS receivers and antennas, the VN-300 enables accurate heading measurements independent of vehicle dynamics or magnetic sensors, providing unrivaled performance in both static and dynamic conditions. provide performance.

The VN-300 is designed for applications requiring a highly accurate inertial navigation solution under static and dynamic operating conditions, especially in environments with unreliable magnetic heading and good GNSS visibility. I'm here. The VN-300 is the first and only dual GNSS antenna inertial navigation system in a single surface mount package. The postage stamp-sized VN-300 SMD requires only a single 3.2 to 5.5V power supply and can be directly integrated into the user's electronic device for unprecedented SWAP benefits.

The VN-300 Rugged is the "plug and play" version of the VN-300 SMD. The VN-300 Rugged is housed in a clamshell precision anodized aluminum enclosure that further protects the internal MEM sensors, GNSS receiver and electronics. Interface to the module is via a locking 10-pin connector and two MMCX connectors for external active GPS antennas.
