Key Features

Centimetre-level Accuracy

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.

* Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. For maximum system accuracy, always follow best practices for GNSS data collection. 1 ppm means 1 mm/km away from base. ppm is limited to baselines up to 20 km
