VectorNav Dual Antenna GNSS/INS (VN-300)

The VectorNav Dual Antenna GNSS/INS (VN-300) delivers accurate position, velocity and attitude in real time. Available in embedded (SMD) and rugged (CR) versions.  It is ideal for UAVs, robotics, surveying, autonomous vehicles and marine systems that require reliable heading and navigation during motion.

Stable Navigation Data for Dynamic Platforms

The VectorNav Dual Antenna GNSS/INS (VN-300) is perfect for applications that require accurate position, velocity and orientation while in motion.  The VN-300 combines precision MEMS inertial sensors, dual GNSS receivers and advanced onboard Kalman filtering.  As a result, it delivers stable navigation data during vibration, rapid movement and short GNSS interruptions.

Key Benefits of the VectorNav Dual Antenna GNSS/INS (VN-300)

  • Dual-antenna GNSS: Provides true heading without reliance on magnetometers.
