SPEEDBOX-RTK real time kinematic slip angle measuring option for the SPEEDBOX

SPEEDBOX-RTK Option:

The RTK option for the SPEEDBOX includes the following in addition to the standard SPEEDBOX features:

The SPEEDBOX-RTK uses innovative cutting-edge "Moving Base Real Time Kinematics" GPS technology to accurately measure vehicle yaw and pitch 20 times per second. These parameters are calculated using very high accuracy position measurements from two separate GPS antennas. The relative positions of the two GPS antennas can be determined within a few millimetres, so for a baseline distance of 1m between the two antennas (typical) the vehicle pitch and yaw can be calculated to an accuracy of a few tenths of a degree. Vehicle yaw and pitch are measured directly and do not require the vehicle to be moving.

Who is the SPEEDBOX-RTK designed for?

The SPEEDBOX-RTK is primarily designed for OEM testing and professional level motorsports or any application where high accuracy real time vehicle attitude and speed measurements are required.

How is the SPEEDBOX-RTK used?

The SPEEDBOX-RTK is connected to a data logging system using any combination of the RS232, CAN, pulse and analogue outputs provided. The unit itself requires no calibration, but the two GPS antennas must be placed a fixed distance apart on the roof of the vehicle (1m is typical). Accurate measurement of the distance between the two antennas is not necessary because the unit will automatically calculate the exact distance itself. When powered up, the SPEEDBOX-RTK will automatically lock onto GPS satellites and use the relative positions of the antennas to calculate vehicle yaw and pitch, as well as heading, gradient, speed and position which are calculated from one antenna. A status indicator light on the SPEEDBOX-RTK informs the user of the current output status.

Key features

• 20Hz yaw and pitch output. The RTK system calculates vehicle yaw and pitch from relative positions of the antennas and outputs a reading at 20Hz.

• 20Hz heading and gradient output. The base GPS receiver in the RTK is used to calculate the heading and gradient based on the speed calculations.

• 20Hz GPS speed and position output. The GPS speed and position information is calculated and output at 20Hz.

• Wide range of output formats. Available output formats include CAN, RS232, pulse and analogue. Custom output messages, such as NMEA over RS232, can be added on request.

• Configurable. The SPEEDBOX-RTK is supplied with PC configuration software which allows details of the outputs to be configured. Full configuration instructions are provided.

• Upgradeable firmware. The firmware of the SPEEDBOX-RTK is flash upgradeable from the serial port of a PC. Firmware updates are provided free of charge and full reflashing instructions are provided.

• Software and documentation. The SPEEDBOX-RTK is supplied with a comprehensive software CD providing full instructions for installation, configuration, use and output data processing (if required).

Recommended Optional Extra

We recommend the use of our RTK dual antenna strip. It has been designed specifically for use with the SPEEDBOX-RTK.

The dual antenna strip consists of:

• 2 of our low noise antennas
• CNC mounting bosses for the antennas
• cables
• magnetic strip for mounting

The antennas are assembled with a fixed baseline of 800mm for direct mounting to a vehicle roof.
