DUAL GNSS / INS
VN-310
The VN-310 is a tactical-grade, high-performance Dual Antenna GNSS-Aided Inertial Navigation System (Dual GNSS/INS). Incorporating the latest inertial sensor and GNSS technology, the VN-310 combines 3-axis accelerometers, 3-axis gyros, 3-axis magnetometers and two Multi-band L1/L2/E5b GNSS receivers into a compact embedded module or ruggedized packaging option to deliver a high-accuracy position, velocity and attitude solution under both static and dynamic conditions.
