Our GNSS-aided Inertial Navigation System combines multi-frequency GNSS, inertial and wheel speed data for reliable position, velocity and heading data in areas with poor GNSS. VBOX Omega is ideal when you need PNT in any outdoor environment.
Connected to a base station or an NTRIP modem, VBOX Omega delivers centimetre-level positional accuracy.
Wheel Speed Integration
In GNSS denied environments, such as tunnels and deep urban canyons, VBOX Omega significantly improves the accuracy of the estimated speed and position data by combining wheel speed with GNSS and inertial data.
High-grade Inertial Measurement Unit
The integrated IMU offers precise measurements of pitch, roll and yaw and also helps fill GNSS gaps.
Resiliant GNSS Performance
Tracking the GPS, GLONASS, BeiDou and Galileo constellations, VBOX Omega offers robust position accuracy and precise measurements of speed and distance, at an extremely competitive price.
