|Abstract: ||The GPS devices are well known and used by many people, especially for
navigation. These are commercial GPS devices, which can be found at decent prices.
Professional devices also exist for geodesic applications, and even for dynamic data acquisition.
These are much more precise devices, but also very expensive.
This paper presents a complete acquisition system developed by the authors, using a high
performance GPS device, available on the market, a portable mini-computer (UMPC) and
dedicated software. The GPS sensor is one oriented to OEM users, for machine operation and
guiding and agricultural applications. The sensitivity is very high and the registration rate is 5
Hz. It is connected to a computer through serial interface.
The software application developed for this system takes the information from the GPS sensor
using special sentences defined by the NMEA messages standard. Information about position,
velocity and acceleration are displayed in real time on the computer display and all useful data
acquired are saved in a text file. These data are imported then in a special CAD application, for
post-processing. The system was used in various studies regarding vehicle dynamics or
efficiency and traffic or noise analysis. Some diagrams and reports obtained after postprocessing
are also presented in the paper.|
