Introduction
This user manual serves as an aid in commissioning the ADMA (

M
otion
A
nalyzer)
gyro system.
The first part of the manual describes a routine for testing whether the ADMA gyro system's inertial
sensors are operating without error. This function test is also a good way to become familiar with
ADMA and to gain experience in setting up the ADMA.
The second part of the manual describes a typical configuration of a test vehicle, including auxiliary
sensors such as an external speed measurement system or a GNSS.
The ADMA (

nalyzer) is a strapdown inertial measurement system
equipped with robust gyros and accelerometers and adapted specially for automotive measurements.
To maintain system performance even during complicated test manoeuvres, a DGNSS has been
integrated.
The ADMA uses an extended Kalman filter for data fusion of INS data and (D)GNSS data / external
velocity data. The ADMA provides not only raw data of the 6 inertial sensors, but a variety of motion
states, other additional states and system status. Measurement data supplied by the ADMA include:
•
ADMA status
•
Rates
•
Accelerations
•
Tilt, yaw und side slip angle
•
Velocity (GNSS, Inertial, external source)
•
Position absolute (GNSS and Inertial)
•
Position relative (GNSS and Inertial)
•
Standard deviation of tilt, yaw, velocity and position
•
Sample time, system temperature
•
GNSS time and ADMA time (based on GNSS time)
•
Time reference of event inputs
With the data available, a multitude of applications can be covered, such as:
•
Vehicle dynamics
•
Measurements of vehicle body motion
•
Analysis of driving comfort
•
Measurements of carriageways and routes
•
Validation of simulation models
•
Reference for developing driving assistance systems (e.g. ABS, ASR, ESP; AEB, LSS,..)
•
Brake test
•
Precise speed measurement
•
Acceleration and deceleration testing
•
Road holding tests
•
Tire testing
•
ADAS (Advanced Driver Assistance Systems) evaluation
