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.

车载单元的开发是为了实时获取有关车速、位置和RPM的数据。 此外,通过与固定单元共享信息,还可以参考输入和输出屏障来理解车辆的位置。

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.

Dynatrack基于GNSS的“先进技术”技术,接收器使用代码和相位信号来确定车辆位置(载波相位多普勒技术),同时通过针对动态性能优化的Von Kalmann滤波器改进速度计算。

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.


除此之外,Starpass还指导驾驶员完成必要的程序,以便按照标准正确执行测试。 测试驱动程序提供:


2) 检查背景噪音和其他环境参数。

3) 实时检查测量子系统的状况和质量(远程操作,GPS解决方案,信号分析仪)


5 )进行加速试验并与之前的试验进行比较


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.

Soundbook该系统不仅可用于符合单一标准的单独通过测试,还可用于根据各种标准进行不同的现场测试:SAE J 1470,2001 / 43CE、ISO 13335、ISO5130和 其他应要求。


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:

此外,Soundbook 还可以与来自车载单元提供的辅助通道的数据共享速度和位置以用于其他用途。 通过使用与系统扩展端口连接的可选模块,您可以获得:

- Information from the vehicle through OBD II 

  通过OBD II提供车辆的信息

- 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.
