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.

ADMA Features

  • Measurement of vehicle motion in three axes, even during GNSS signal loss
  • Dynamic attitude and heading angle determination
  • Precise acceleration, speed, and position data due to extended Kalman filter

  • High precision position data (1 cm) with internal RTK2 DGNSS receiver and GNSS Base Station
  • Robust inertial sensors and strap-down technology without moving parts

ADMA Highlights

  • Data output rate up to 1000 Hz
  • Data output via 5 CAN bus interfaces and Ethernet
  • Configuration via Ethernet
  • Forwarding of GNSS correction data and relative data calculation (e.g. distance) via WiFi in real-time for multi-vehicle operation
  • GNSS synchronized DAQ synchronization signal, the high clock frequency
  • Inputs for the recording of analog signals
  • The output of GNSS raw data via Ethernet interface
  • Indoor GNSS interface
  • Dual GNSS antenna option
  • Multi GNSS capable (GPS, GLONASS, GALILEO, BEIDOU)
  • Data latency < 1 ms
  • Compatible with all common steering and driving robots

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.
