ADMA-G: GNSS/Inertial System for vehicle dynamics testing
ADMA stands for Automotive Dynamic Motion Analyzer. This acronym refers to our highly precise Inertial Measurement Unit (IMU) using DGNSS (Differential Global Navigation Satellite System). The system was developed particularly for Vehicle Dynamics Testing in the automotive sector. Our ADMA system allows for constant measurement of acceleration, speed and position of moving vehicles in all three dimensional axes. Pitch, roll and course angles can be continuously and precisely measured with ADMA as well as course and side-slip angles as well as angular rates.
This makes GeneSys ADMA system the best choice where challenging measurements with maximum accuracies are required.

ADMA Applications
The strap-down technology ensures that the ADMA is stable and resistant to unwanted vibration during use. This means the ADMA is very well suited for evaluation of Vehicle Dynamics and Driver Assistance Systems. The ADMA system is successfully used for Motorsports, Driver-less Systems, and Construction Machines. It is proven itself in the areas of Route, Track Wear, and Railway measurements.

Out Products for any Requirements
The ADMA models differ in the performance of the applied inertial sensors. Higher precision sensors are less sensitive to GNSS interferences or outages. All models are available with variable GNSS accuracy, ranging from simple L1 receivers with meter accuracy to L1/L2 RTK receivers with centimeter accuracy. Our gyro systems do not require an export license.
ADMA-options – extending capabilities
The new generation of ADMA3 devices now allows our customers to meet their new and changing needs. Our focus is on straightforward use and increased productivity. The add-on functions can be activated quickly and conveniently by entering a license key. This is possible at any time without modifications to the hardware. A high degree of flexibility is thus ensured.
