High-Precision Inertial Reference Systems for Vehicle Dynamics Testing

The GeneSys Automotive Dynamic Motion Analyzer, ADMA, is a high-precision inertial reference system developed specifically for automotive testing.

Combining DGNSS with fibre-optic gyroscopes and robust strap-down technology, ADMA continuously measures vehicle position, velocity and acceleration in all three axes. It also provides precise pitch, roll, heading, side-slip angle and angular-rate data.

ADMA-G-PRO+ and ADMA-G-ECO+ are designed for demanding applications that require accurate and reliable vehicle-motion data, even during temporary GNSS signal loss.

Applications

• Vehicle dynamics testing
• ADAS and driver-assistance system evaluation

Configurable Performance

ADMA-G models differ in the performance of their inertial sensors. Higher-precision sensors provide greater stability and accuracy during GNSS interference or signal loss.

Different GNSS configurations are available, from L1 receivers with metre-level accuracy to L1/L2 RTK receivers with centimetre-level accuracy.
