SPEEDBOX Speed Sensor

Speedbox

The SPEEDBOX is a very high accuracy non-contact speed sensor that has been designed for professional automotive testing as well as other industrial and high-end motosport applications. It outputs a low latency, non-interpolated speed measurement comprised of GPS and inertial data combined using an adaptive filter for exceptional performance even in non-GPS ideal environments. Packaged in a high quality machined aluminium enclosure, it offers an extremely high reliability design based on our years of racing experience. The high accuracy speed measurement is output in a variety of forms suitable for integration into most datalogging and display systems; CAN, RS232, analogue and a fully configurable digital pulse output are all provided as standard.

The SPEEDBOX uses Race Technology's very own high accuracy 20Hz PurePhase GPS solution, optimised for speed measurement, which outperforms even top of the range 'survey-grade' GPS receivers in this respect. This unique GPS technology outperforms "GPS-only sensors", offering lower noise, lower latency and superior bandwidth, and is far more resistant to drop outs. It offers an ideal replacement/upgrade for 5th wheel, optical and gps-only sensors in a wide variety of automotive testing applications, including brake testing, chassis dynamics, accident reconstruction, tyre testing and stability management testing, to name but a few.

The SPEEDBOX avoids the inaccuracies, wear and calibration requirements of devices such as wheel speed sensors, requiring only a good view of the sky to give speed output typically 40 times more accurately than a calibrated wheel speed sensor.

Evolution

SPEEDBOX Versions

The SPEEDBOX is available with a number of options, namely RTK, IMU, and the new INS system. The RTK uses 2 GPS receivers as a "digital compass" to measure yaw and body slip angle. The IMU option is a very high precision inertial sensor used to measure accelerations and roll/pitch/yaw rates. The RTK and IMU options can be used on the same unit. Finally the SPEEDBOX INS options (3 models are available - 1 standard, and 2 tactical grade) are our flagship products, they use precision roof mounting sensor assemblys that combine the GPS and inertial measurements to produce very high accuracy measurements of speed, position and roll/pitch/yaw all at 200Hz.

A summary of the functionality of each option is shown in the table below:

* SPEEDBOX MINI available with RTK and INS options only, IMU and IMU/RTK options not available.

The figures given are for 50% CEP accuracy and with a good GPS signal.

Note 1: for the RTK option only either Pitch or Roll is available at one time, not both. For the INS option, all outputs are available simultaneously.

Note that 20Hz measurements need a GPS fix to be valid, all 200Hz measurements are from the inertial sensors and robust to GPS outages making them far more suited to highway testing.
