The SafeTRIP OBU Demonstrator

For the demonstration of the advantages of the SafeTRIP platform using real applications, an OBU demonstrator has been developed. The approach chosen for demonstrator development was to rely as much as possible on existing components and to focus on integration and application development rather than miniaturization. Leveraging the modular approach of the reference architecture and the standards based software interfaces of the Service Enabling Layer middleware the reference architecture could easily be mapped to a physical demonstrator architecture based on hardware platforms from the SafeTRIP partners.

Depending on the communication requirements of the demonstrated applications, not all demonstrator components are required during the field tests. In the following, the full demonstrator configuration comprising satellite broadcasting, messaging return-link and connection-oriented communication is described. It consists of the following physical hardware components:

-     DT4900 S-band Terminal Platform comprising DVB-SH receiver and S-MIM modulator for broadcast and messaging communication as well as a general purpose compute platform for Service Enabling Layer and applications.

-     SR40 IP Modem for connection-oriented bi-directional satellite communication.

-     MCU3 car gateway and processing unit with 3-buttons panel and touch screen.

-     WiFi Router to allow access to Live TV and other multi-media content from multiple mobile devices (e.g. inside buses).

-     GPS antenna for MCU3.

-     S-band antenna.
