ADMA-Speed: Speed and Braking Distance Sensor

Precise Speed Measurement and more

ADMA-Speed is a GPS speed sensor with integrated inertial sensors. It is optimized for brake tests.
For easy installation, the inertial sensors are integrated in the GPS antenna.

All motion data of the vehicle is calculated by means of the tried and tested ADMA technology. In the basic version accelaration, speed and braking distance is transmitted via the CAN and Ethernet interface. ADMA-Speed eliminates the known disadvantages of GPS speed sensors.

Optionally, ADMA-Speed can be expanded to a fullfledged GPS-aided inertial system, e.g. for vehicle dynamics testing or verification of ADAS systems.
