VBOX 3i Single Antenna

The VBOX 3i Single Antenna (RLVB3i) is extremely versatile and offers position accuracy of up to 50 cm.

It is the industry standard data logger for performance, braking and tyre testing, thanks to its impressive accuracy and range of features along with an attractive price point. The VBOX 3i Single Antenna is easy to set up and use, which is why it is used by almost every vehicle and tyre manufacturer worldwide.

When used with a DGPS Base Station, VBOX 3i Single Antenna units can achieve a positional accuracy of 50 cm. As with previous VBOX models, VBOX 3i is compatible with all existing peripherals, including our Multifunctional Display, 16-bit Analogue Input Module, 4 Channel Frequency Input Module, Thermocouple Interface, and Yaw rate sensor.

For accurate testing, even in areas where the view of the sky is obstructed, VBOX 3i can gather additional information from an Inertial Measurement Unit (IMU) and combine this with the GPS data in real-time to improve the quality of the measured parameters.
