High Accuracy Speed Sensor

The SPEEDBOX2 is the successor to Race Technology’s highly regarded SPEEDBOX which is already used by many automotive OEMs and vehicle testing organisations worldwide. The SPEEDBOX2 is a high accuracy, low latency GPS and inertial transducer suitable for interfacing with a wide range of data acquisition and logging systems. Primarily, the SPEEDBOX2 is used to measure speed and distance travelled, however other outputs include position, gradient, heading and acceleration. Modular add-ons are also available to allow measurement of vehicle roll, pitch and yaw angles and rotation rates.

GPS is now the technology used almost universally where accurate measurements of vehicle speed and distance travelled are required.  GPS has largely replaced 5th wheel and optical technology over the past decade, offering higher accuracy, easier installation, lower latency and lower running costs compared with the legacy technologies.

What is unique about the SPEEDBOX2 product range is that it uses the most advanced GPS technology available and combines this information with accelerometer data using a Kalman filter. The result is a system which outperforms GPS-only sensors in every regard.  Accuracy, latency and signal to noise ratio are all dramatically improved.  Output accuracy is also maintained even during temporary GPS signal outages.
