SD Card Logging
Which VBOX II is right for you?
VBOX IISX - Single Antenna
VBOX IISX logs data at 20 times a second and features a built-in display, SD card logging, high speed brake trigger input, CAN interface and two sets of analogue and digital outputs.
Due to its small size and simple installation, VBOX IISX is ideally suited for use in cars, bikes, off-road vehicles and boats.
It's multi-constellation GNSS engine gives a high standalone positional accuracy of <1 m, and <0.5 m when utilising the free WAAS/EGNOS correction service.

Brake & Tyre Testing
An update rate of 20 Hz is still plenty fast enough for brake testing. You don’t quite get the phenomenal ±1.8 cm acuracy of the VBOX 3i, but for many purposes the ±10 cm achieved is more than adequate. The VBOX IISX has a high speed brake trigger input, which scans for a braking event 100,000 times a second.
Performance Testing

VBOX IISX - Dual Antenna
The VBOX IISX Dual Antenna has an update rate of 20 Hz and features a second GPS engine.
By using two GPS engines configured in a 'fixed baseline RTK setup', extra parameters such as slip and pitch angle (or in an alternative configuration roll angle) can be measured. This makes it ideal for dynamic testing, steady-state cornering, and the measuring of trailer angles (two systems needed).
Its positional accuracy is <1 m, utilising the free WAAS/EGNOS correction service.

Handling and Dynamics
By utilising two GPS engines, the VBOX IISX Dual Antenna measures all the normal GPS parameters, such as speed, position and distance, plus the direction both antennas are pointing and the angle between them. All parameters are captured at 20 Hz.
