VBOX 3iS
VBOX 3iS
The VBOX 3iS is a compact GNSS-aided inertial navigation system (INS) with a built-in OLED display.
Combining wheel speed and survey-grade 100 Hz GNSS measurements with an Inertial Measurement Unit, the VBOX 3iS offers accurate position, speed, acceleration, attitude, and angular rate data.
In GNSS denied environments, such as tunnels and deep urban canyons, combining wheel speed information with GNSS and inertial data in a Kalman filter yields a significant improvement in the accuracy of the estimated speed and position.
Only 13 cm in length, the sensor is easy to mount and transport, making it ideal for automotive, motorsport, marine, and telematics testing and development.
