ADMA 3.0 USER MANUAL ADMA laboratory bench test The routine described below is intended to test the functionality of the inertial sensors of the gyro system, i.e. the accelerometers and gyroscopes. This function test is also a good way to become familiar with the ADMA and to gain experience in setting up the ADMA via Webinterface.
ADMA 3.0 USER MANUAL 7.2 ADMA configuration for bench testing 7.2.1 Configuring measurement data transmission via the CAN interface Go to menu DATA LINK . Activate CAN data out for testing. This sets up the ADMA to transmit the data via the CAN port. Please note, that COM and CAN mode can only be used exclusively! The default CAN settings are: •...
ADMA 3.0 USER MANUAL 7.2.2 Selection of data packets to be transmitted The Data dialog is used to individually select the data packets which shall be transmitted by the ADMA. Data packets which are not required can be deactivated in order to reduce the transmission data volume.
ADMA 3.0 USER MANUAL 7.2.3 Auxiliary systems This dialog is used to specify parameters which are related to auxiliary systems such as DGNSS settings and external velocity systems. For the function test, it is necessary to deactivate all auxiliary systems as described below: •...
ADMA 3.0 USER MANUAL 7.2.4 Parameters The values of roll and pitch angle misalignment should be determinate via Auto Roll/Pitch alignment. Figure 12 Dialog: Parameters Page 26/137 Document Revision 2.01 | 2021...

ADMA 3.0 USER MANUAL 7.4 Static test 7.4.1 Transient condition of the Kalman filter The Kalman filter of the ADMA can be activated without auxiliary systems like an external velocity or a (D)GNSS. It is possible to experience transient effects in the first few minutes (60-120 seconds). After this transient phase, stable values will be shown.
ADMA 3.0 USER MANUAL 7.4.3 Checking the accelerations The ADMA should be positioned on a laboratory bench or similar facility, thus being placed on a close to horizontal surface. In addition, keep a flat support surface ready so that the ADMA remains level even when tilted.
The measured rotational speed of all axis should be between ±0,1°/s. Without special software and hardware, it is not possible to test gyros accurately, so it is necessary to send the ADMA to GeneSys for calibration on a regular basis. Page 32/137...
ADMA 3.0 USER MANUAL 7.5 Dynamic Test As part of the dynamic test, the ADMA undergoes defined linear and rotary motion, i.e. along or about the systems sensor axis. The rotational speeds are checked first, beginning with the X-axis (roll), followed by the Y (pitch) and (yaw) axes, and then followed by the acceleration check in the same sequence of axes.
Page 34
ADMA 3.0 USER MANUAL 7.5.2 Checking the accelerations The system should be move linearly along the individual axes in the sequence X, Y and Z. The plotted data could appear as follows: Diagram 2 Plot - Accelerations body X/Y/Z This data plot shows that ADMA detects negative as well as positive accelerations along the three measurement axes.
ADMA. Safe and secure installation of the ADMA is essential to receive reliable data. Figure 19 ADMA-G point of installation The GNSS antenna must be mounted on the roof of the vehicle. For best performance, it is necessary to mount the GNSS antenna(s) away from any object that may shadow the satellite signal.
ADMA 3.0 USER MANUAL 8.1.2 ADMA-Speed Mount the ADMA-Speed antenna in a suitable position on the roof of the vehicle. The ideal position is in the front or back of the roof, on a rigid area away from any objects that may shadow the GNSS signal such as roof bars.
ADMA 3.0 USER MANUAL 8.1.3 ADMA-Slim The ADMA-Slim can be installed in a suitable position anywhere in or on the roof of the vehicle. The GNSS antenna must be mounted on the roof of the vehicle. For best performance, it is necessary to mount the GNSS antenna(s) away from any object that may shadow the satellite signal.
We recommend to keep the system at least 30 cm away from glass surface or outer edges of the vehicle. • It is important that both antennas are from GeneSys and of the same type. Using two different types of antenna may cause the solution to fail. •...
ADMA 3.0 USER MANUAL 8.1.5 External velocity measuring system Usually, the external speed measuring system is attached to one side of the vehicle. For slalom tests involving a higher risk of damage to the sensor, a point at the front / rear of the vehicle can be used. 8.1.6 Auxiliary antennas The antennas for the ADMA, GNSS, Radio Modem or GPRS-Modem and Wireless LAN should be spaced out across the roof of the vehicle ideally across around 1 m.
Technical Documentation. 8.2.3 ADMA and external velocity measurement ADMA-G systems can process analogue and digital velocity signals - including 2-axis signals - via the External Velocity interface. For this purpose, connect the external velocity sensor to the ADMA-G Ext.Vel.
ADMA 3.0 USER MANUAL 8.2.4 ADMA and DGNSS For using the DGNSS or RTK-mode of the ADMA a Radio Modem, GSM/GPRS-modem or a Wireless Accesspoint is required to receive correction data. The modem LED indicates the supply of the modem with voltage.
ADMA 3.0 USER MANUAL 8.3 Modify threshold for AutoInit, Heading ctrl. and Dual Antenna use The AutoInit function of the ADMA is used to automatically set the ADMA inertial states after system start-up, including the yaw angle (Heading). This is only possible with an adequate vehicle velocity, since the yaw angle will be overwritten with the COG (GNSS Course Over Ground) value.
ADMA 3.0 USER MANUAL 8.4 Standstill detection The following describes standstill detection thresholds and their correct entry, which will increase the data integrity. Standstill allows a special form of augmentation for use with the Kalman filter, the so called Zero-Velocity-Update. This mode of the Kalman filter update increases the stability of the measurement mode in case of standstill.

Page 46
ADMA 3.0 USER MANUAL 8.4.5 Manual determination of the standstill thresholds Standstill detection (Standstill bit) must be “1” with the engine running at vehicle standstill. To determine the maximum rate at standstill, the horizontal rates of the vehicle must be considered at standstill, with the engine running.
ADMA 3.0 USER MANUAL 8.5 Modify thresholds for quality indication After starting the measurement, the position-, tilt- and velocity-status is available after 120 sec. This status is based on the Kalman filter’s internal estimation of the quality of the state variable (standard deviation Stddev).
Page 48
ADMA 3.0 USER MANUAL With the GNSS re-entering after a GNSS outage the position quality will increase again. This leads to smaller standard deviations of the ADMA position and thus affecting the position standard deviation. Note: The position error can be reduced to a linear error behaviour by using an external velocity signal. Subsequently, a better position quality can be expected over a certain period of time.
ADMA 3.0 USER MANUAL 8.6 Relative Coordinate System The ADMA can output position data referred to a relative coordinate system defined by the user. In order to set a local coordinate system, two parameters are required: • The origin (zero point) of the relative coordinate system defined by latitude and longitude. This origin must be in a area within a few kilometers to achieve the +/-1cm position accuracy.
ADMA 3.0 USER MANUAL The user defined relative coordinates system can be defined via web interface page PARAMETERS \ System Parameters. Enable the user defined relative CS, and type in the latitude, longitude and heading values. The heading angle is the rotation of the X-axes relative to North. For example, leaving this value 0 will set the X-axis to point North, and the Y-axis to West.
ADMA 3.0 USER MANUAL 8.7 Compensating an ADMA misalignment 8.7.1 ADMA misalignment As described earlier, an exact alignment of the measurement axes with the vehicle's axes is rarely achieved. However, it is possible to compensate such alignment errors mathematically. Compensation values can be entered in the Offsets dialog in the ADMA Webinterface (menu PARAMETERS).
ADMA 3.0 USER MANUAL If a 2-axis speed sensor - for instance, one made by Corrsys - is employed, its mounting can be rotated. The corresponding misalignment can only be determined during a straight-ahead run. Similar to the misalignment in the case of the ADMA, a misalignment causes the vehicle's X-axis speed to produce a component along the sensor's Y-axis.
ADMA 3.0 USER MANUAL 8.8.1 Mounting offset angle The offset values for the roll axis (X) and the pitch axis (Y) can be determined automatically using the setup function "Auto Roll / Pitch Alignment". The compensation value of the yaw axis (Z) must be entered.
ADMA 3.0 USER MANUAL 8.8.3 Single antenna mounting offsets The position vector for the GNSS antenna consists of all three components (X, Y, Z) and refers to the ADMA. Figure 38 Mounting offsets ADMA-GNSS-Antenna Document Revision 2.01 | 2021 Page 55/137...
ADMA 3.0 USER MANUAL 8.8.4 Dual antenna mounting offsets The easiest way to install the dual antennas is to place both antennas on the same longitudinal axis at the same height. The primary GNSS antenna should be installed behind the second antenna with a minimum distance of 50 cm to a maximum distance of 200 cm.
ADMA 3.0 USER MANUAL 8.8.4.1 Determining the offset between the GNSS Antennas and ADMA 8.8.4.2 Mounting offsets Primary GNSS Antenna to ADMA The Primary GNSS Antenna always refer to GNSS ANT1 interface of the ADMA. This offset must always be determined. Figure 40 Mounting offsets Primary GNSS Antenna to ADMA Document Revision 2.01 | 2021 Page 57/137...

ADMA 3.0 USER MANUAL 9.6 Signal Out The Signal OUT Ports of the ADMA can be used as Digital output. The following functions can be configured via Webinterface for Signal Out Port: • Synchronization output to indicate the ADMA's sampling time point, thus allowing simple synchronization with peripheral measurement systems which can be triggered externally.
ADMA 3.0 USER MANUAL 9.7 Signal In The Signal In Ports of the ADMA can be used as: • Synchronization input to receive clock signals from an external data recording or measurement system to permit offline synchronization with other data sources. Note: This input only registers one pulse per ADMA cycle.
ADMA 3.0 USER MANUAL 9.8 External velocity If the ADMA is supplied with an external velocity signal, the orientation angles for roll and pitch do not drift, thus permitting measurements over longer periods. Supply of an external velocity signal allows the ADMA to calculate a relative position using the method of dead reckoning.

ADMA 3.0 USER MANUAL 10.4 POI-transformed ADMA data Following the calculation of data valid for the ADMA coordinate system origin, a defined subset of data can be transformed from the ADMA origin to a POI (Point of Interest), even though this requires acceptance of less precision of the transformed data.
ADMA 3.0 USER MANUAL 10.5 Position information 10.5.1 WGS84 (World Geodetic System of 1984) Polar coordinates (longitude, latitude, height above mean sea level) are used as a standard technique of indicating positions for worldwide navigation. Most commercial GNSS receivers also output their measured positions in this format.
ADMA 3.0 USER MANUAL 10.5.2 ETRS89 (European Terrestrial Reference System) The European Terrestrial Reference System 1989 (ETRS89) is an ECEF (Earth-Centred, Earth-Fixed) geodetic Cartesian reference frame, in which the Eurasian plate as a whole is static. The coordinates and maps in Europe based on ETRS89 are not subject to change due to the continental drift. Since then ETRS89 and ITRS diverge due to the continental drift at a speed about 2,5 cm per year.
ADMA 3.0 USER MANUAL 10.6 Relative, metric coordinate system For some applications, it is not useful to specify positions in terms of decimal degrees of longitude and latitude. In this case it would be more helpful to specify positions in meters, for example, to indicate braking distances, radii of steady state circular tests and track deviations.
ADMA 3.0 USER MANUAL Measuring mode 11.1 Start sequence After powering up, the system runs through a boot process which ends in standby mode. The ADMA's measuring mode can then be started via the configured data interface or operated with the Start and Stop commands.
