More details

Dynatrack is a special system for pass-by tests based on high accuracy GNSS technology. The Dynatrack system has been specifically designed to allow a single operator to carry out the tests.

The hardware consists of the onboard-unit and the base station. The base station is designed to acquire and analyze the sound pressure level signals through Soundbook, the multi-channel analyzer, and to transfer them to the mobile unit by means of a specific WLAN technology.

The onboard-unit has been developed to acquire the data concerning vehicle speed, position and RPM in real time. Moreover, by sharing the information with the fixed unit, it is also possible to appreciate the position of the vehicle , making reference to the input and output barriers.

Benefits for users: 
Advanced GPS technology 

The acoustic measurements performed by Soundbook are synchronized through the base station with the onboard unit, by GNSS University Time clock, and with the data concerning car position,speed and PRM.

Dynatrack in based on GNSS’state-of-art’, technology the receiver uses both the code and phase signals to determine the vehicle position (carrier phase Doppler technique), while the speed calculation is refined via a Von Kalmann filter optimized for dynamic performance.

The receiver can manage multiple constellations of the navigation system, which makes use of a considerable number of parallel receiving channels (up to 50 satelliters, including GPS, GLONASS and EGNOS signals).

Besides that, Starpass guides the driver through the procedure necessary in order to perform the test correctly according to the standard. And the Test Driver provides the function of 1).Planning the characteristics and the serviceability of test. 2). Checking the background noise and other environmental parameters. 3). Checking the condition and the quality of the measurement subsystems in real-time (remote operation, GPS solution, signal analyzer), 4).Acquiring speed RPM and sound pressure level data on the microphone line or at different position within the measurement area and 5).Carrying out the acceleration tests and compare with previous ones

Open to meet user’s requirements

The system has been developed not only to be used for individual pass-by test complying with a single standard, but also for carrying out different in-field tests according to various standard: SAE J 1470, 2001/43CE, ISO 13335, ISO5130 and others on request.

It is also possible to share both speed and position with the data coming from the auxiliary channels provided by the onboard unit for other uses. By using the optional modules connected with the system expansion ports,you can acquire:

- Information from the vehicle through OBD II

- acceleration data on 3axis with IMU (Inertial Measurement Unit)

-DC Channels:3 or more channels at 20Hz

-Digital Channels: 2 fast input and 2 fast outputs

It is possible to use second Soundbook analyzer with the onboard unit in the vehicle for parallel inside and outside noise measurement.
