ADMA-Speed: GNSS/inertial navigation system: Precise Speed and Braking Distance Sensor

ADMA-Speed is a GNSS/inertial reference system with integrated inertial sensors. It is optimized for brake tests. For easy installation, the inertial sensors are integrated in the GNSS antenna.

All motion data of the vehicle is calculated by means of the tried and tested ADMA technology. In the basic version of ADMA-Speed: GNSS/inertial navigation system (INS) acceleration, speed and braking distance is transmitted via the CAN and Ethernet interface. ADMA-Speed eliminates the known disadvantages of GNSS speed sensors.

Technical data for ADMA-Speed: GNSS/inertial reference system can be found in the table below or in the data sheet.
