VBOX 3iS Single Antenna RTK (v1)

 VBOX 3iS Single Antenna RTK 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 3iSR offers accurate position, speed, acceleration, attitude and angular rate data.

VBOX 3iSR has RTK and DGNSS for greater positional accuracy when used in conjunction with a VBOX Base Station or an alternative RTCMv3 service like NTRIP. This allows it to be used for robot guidance and as a moving target, as part of a VBOX ADAS setup. 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.

The sensor is easy to mount and transport, making it ideal for automotive, motorsport, marine, and telematics testing and development.
