The Application

The GNSS/CN based road pricing application enables simulating the operation of an on board equipment (OBE) using real positioning data. It supports both real time operation, by means of a physical connection to a GNSS receiver, and operation from logged NMEA positions. This enables its use not only for testing/registering of data on the field but also for reviewing these tests at the laboratory.

Some important aspects in the design of the application are:

• Programmed in java, because of its object-oriented, platform independent characteristics, also providing a great variety of developer tools and free libraries.
• We selected Eclipse as development environment.
• An implementation of a subset of classes included in prCEN ISO TS 17575 Applications Interface Definition for GNSS/CN based EFC was used for managing the geographic information.
  
• A GPL java package has been used for the communication with GPS devices: gpstool from Dinopolis.
