VBOX IISX
20 Hz GPS Data Loggers

With a 20 Hz GPS update rate and options for connectivity, the VBOX IISX is a cost-effective data logger that suits a wide range of requirements.

20 Hz update rate
High contrast OLED screen display & buttons for basic configuration
Connects to all VBOX input modules
Measure slip angle, pitch/roll angle and heading

Key Features

CAN Bus Input

Log up to 16 vehicle CAN parameters, or connect to external modules like the Thermocouple Interface, Frequency Input Module, and Analogue Input Module.

Brake Trigger

By using a physical switch on the brake pedal, a precise start of the 'braking event' can be captured. This is required to get true stopping distance with ±10 cm accuracy.

OLED Screen Display

VBOX II SX features a high contrast OLED screen display and buttons for basic configuration without a PC.

Attitude Angles

You can measure slip angle, pitch/roll angle, yaw rate, true heading, and velocity simultaneously with the dual antenna version.

Real-time Testing

Connects to a laptop or tablet via USB or Serial, making it easy to test in real-time, directly from the test vehicle.

Digital & Analogue Outputs

The digital and analogue outputs (2 each) can be configured to output velocity (or other GPS parameters) for use by additional data logging equipment.

SD Card Logging

Data is stored to SD card in a standard PC format (ASCII text) allowing fast transfer of data to a PC with an SD card reader.

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

This unit is perfect for all variations of performance testing, the accuracy and quick response of the 20 Hz unit gives very repeatable and accurate results, when tested back to back with the VBOX 3i, they are within a few hundredths of a second every time.

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.
