Inertial technology corrected by GPSThe algorithms used by the ADMA have been optimized for vehicle dynamics testing like slalom and steady-state circular testing. Even the Earth‘s gravi-tational acceleration and rotation are taken into account. Due to the fact that the ADMA has no moving parts, the systems are fault-tolerant. So reliability and robustness are assured.

Our latest ADMA 3.0 generation also uses the CAN bus or Ethernet interface to output the data. This guarantees easy and reliable operation and data syn-chronization utilizing conventional data acquisition systems.

The Measurement SystemHow does it work?Thanks to a keen sense of balance, humans orientate themselves very quickly and control their movements with extreme accuracy.

ADMA is based on this same principle. Like the inner ear, the accelerometers of the inertial platform measure linear motion and create a reference to gravitational ac-celeration. Three orthogonally positioned gyroscopes sense the rotational motion. From this, speed, location and spatial position are calculated in real time by the

What is ADMA? ADMA stands for Automotive Dynamic Motion Analyzer. This acronym refers to our highly precise Inertial Measurement Unit (IMU) using DGPS (Differential Global Positioning System). The system was developed particularly for Vehicle Dynamics Testing in the automotive sector. The Genesys ADMA system allows for constant measurement of ac- celeration, speed and position of moving vehicles in all three dimensional axes. Pitch, roll and course angles can be con-tinuously 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.

At the heart of ADMA are three gyro-scopes, all recording rotational motion in space.

The gyro system also includes three accelerometers to record linear move-ments.

Absolute position is accurately determined by an internal GPS receiver by means of WAAS or RTK DGPS correction. All components for DGPS data acquisition are included. If required, the ADMA system is also available with an external GPS receiver.

Inertial sensor signals and GPS information are applied by an integrated processor unit featuring DSP and FPGA to continuously determine the orientation angle, speed and position.

signal processor via Kalman filter with centimeter precision.

Potential sensor drift is compensated for by using GPS. This is similar to visual information in support of sense of balance, of humans. In this regard, it does not make any difference if the GPS signal is disturbed or briefly interrupted. As such, the acceleration dependency and high data latency of the GPS signals do not have any significant impact on the measurement.

The ADMA models differ in performance of the applied inertial sensors. Higher precision sensors are less sensitive to GPS interferences or outages. All models are available with variable GPS accura-cy, ranging from simple L1 receivers with meter accuracy to L1/L2 RTK receivers with centimeter accuracy. Our gyro sys-tems do not require an export license.

Precise altitude and position determination

GPS-Base

The GPS outdoor base station provides RTK2 DGPS correction data. In combination with the mobile GPS receiver, a high positional accuracy data of up to 2 cm is achieved. Data transmission takes place via an internal RF modem or optionally via up to three internal GPRS modems. The system has been tested and proven in mobile applications.

ADMA-PP

The ADMA-PP post processing soft- ware merges ADMA inertial data, GPS data and external reference data off- line. Using this method, calculations can be made that are not possible in real-time operation. Post processing ensures data integrity and conside-rably increases accuracy. A further advantage: RTK DGPS correction data do not have to be applied in real-time.

GPRS-DGPS-Box

The GPRS-DGPS-Box can be con- nected to all ADMA models. It receives DGPS RTK2 correction data from stationary GPS receivers or RTK network providers like SAPOS and ASCOS, SmartNet or TopNET. With the RTK2 license activated, the system provides position data, with centimeter accuracy, in real-time.

ADMA-Baro

The ADMA-Baro module is used to determine altitude profiles via baro- metric air pressure. Used as an ADMA accessory in combination with the ADMA-PP post processing software or ADMA-PP light, this module is perfectly suited for capturing accurate measurements of the critical height data, particularly in the event of limited GPS reception.

Mounting accessoriesFor all ADMA systems, various accesso-ries are available for installation in the test vehicle. These installation options are critical for safety. And, thanks to quick and easy mounting, make it possi-ble to focus on what is really important: productive testing.

Seat rail adapter with ADMA mounting plate Provides secure fit even in the event of impacts and vibrations. The fixture can be easily installed and is suitable for almost any vehicle type, including convertibles.

Mounting plate with quick-installation mounting poleThis 8 mm metal plate with dimensions of 28 cm x 28 cm, can be quickly and easily installed in the test vehicle, e.g. in the footwell or trunk. The mounting pole has a span of 100 to 175 cm. Other spans are also available on request.

Installation support for ADMA and data acquisition systems with quick-installation mounting poleThis option combines the ADMA system and the data acquisition system into one unit. This way, short installation times can be achieved if the total measurement system must be relocated.

information received from auxiliary sensors like barometers or odometers may be added to the calculation.

Compared to the real-time solution which is also available, the offline calculation offers two distinct advantages.

1) Firstly, GPS correction data can simply be downloaded for each respective mission. This facilitates installation when conducting the measurement. In contrast to post-processing, GPS correction data have to be consistently supplied during real-time driving measurements via radio or GPRS connection. GPS correction data reception may not be available on public roads.

Verification of simulation models

Underground and tunnel survey

System requirements Windows XP, Windows 7 USB port for license dongle

2) Secondly, ADMA-PP calculates the position both forward and reverse in the time-domain. This leads to considerably higher accuracies compared to the real-time method. Signal data integrity is improved and much higher accuracies can be achieved in the event of GPS signal drops or interference.

Increased Accuracy

More and more often, the GeneSys ADMA system is used to validate Driver Assistance Systems as well as surveys on public roads. In order to achieve required accuracies, Gene-Sys has developed the ADMA-PP post processing software. ADMA-PP optimizes the recorded ADMA data by adding GPS correction after the acquisition.

ADMA-PP combines the inertial and GPS data post-measurement, using identical online and offline algorithms.

The core component of the software is a Kalman filter which optimizes the merging of GPS and inertial data. Additionally,

Precise Altitude Determination

ADMA-Baro is a barometric measuring unit for precise measure-ment of the roadway or track. It consists of a stable housing that records air pressure by means of Pitot tube precision pressure sensor. Using this method, the altitude of the sensor above sea level can be precisely measured using the barometric equation. If the GPS reception is good, weather-related air pressure fluc- tuations are compensated. In the event that the GPS reception should fail, errors in measuring the altitude are considerably limited by means of barometric height determination.

The ADMA-G-EntryLevel system re- quires good GPS reception and GRS-1 can be used to trace pedestrians.

Measurement Data Recording DEWETRON offers various data acquisition systems like DEWE2. These distinguish themselves by absolute synchrony of all data, either ADMA data, vehicle data (CAN, FlexRay, XCP) analog data (e.g. Signalgong) or video data (e.g. Dashboard).

Thanks to GPS-Sync-Clock WLAN transmission, the data of all devices are synchronously calculated, displayed and recorded on a DAQ. By means of the DEWEsoft software, all data including vehicle movements are visualized and recorded and the ADMAs are controlled. Individual online and offline calculations are possible.

CAPS Components Possible Applications Possible Applications

The CAPS test system can also be deployed for precise lane tracing or measurement of vehicle lane deviation. Instead of the distance to other vehicles or pedestrians, the distance to a lane or track is determined in this case.

The components are identical: ADMA, DEWETRON DAQ logging by means of DEWEsoft software, DGPS correction data. However, no Wi-Fi transmission to other vehicles or pedestrians is required.

The reference lane for measuring the vehicle deviation can be generated in various ways: by means of ADMA measurement, KML import or by means of calculation from the covered track (straight, circular).
