About VBOX

The VBOX is based on a survey grade GPS engine with gives an extremely accurate velocity measurement (see about GPS). Since the launch we have sold over 1200 systems to vehicle manufacturer's, tyre companies, magazines and race teams (see customer list). making the VBOX the highest selling GPS based test equipment available today. The VBOXIII sets new standards of accuracy with a velocity accuracy of 0.1kmh, and a braking distance accuracy of less than 5cm. We are the number one choice for speed measurement systems in the world.

We have the most comprehensive and easy to use software available for speed measurement equipment, developed by our team of in-house engineers over the last four years. With this software you quickly and easily measure Accleration, Braking distances, Laptimes, Peak and average g-force, Circuit Position, Coastdown tests and many more.

The VBOX can be used to measure a number of different parameters of a vehicle's performance, both straight line acceleration/braking and cornering. Complicated tests can be set up in a number of minutes, using comprehensive templates, and to trigger at a certain point on a test track, you can define a "virtual" gate which is referenced using the GPS.

The VBOX can measure the following parameters without the need for any other sensors:

  • Velocity
  • Distance
  • Time
  • Position
  • Heading
  • Height
  • Lateral acceleration
  • Longitudinal acceleration
  • Vertical velocity
  • Radius of turn
  • Circuit position
  • Track layout
  • Lap time
  • Coastdown calculations

There are a number of external modules which connect via CAN to the VBOX and allow many other parameters to be logged, and there is a range of displays for in car use.

The VBOX can be used to display results in real time via a serial connection to a laptop computer or the data can be logged to internal memory (removable Compact flash or RAM), and then analysed in post processing.
