SUMMARY An intelligent transport system open platform integrating the S-band Mobile Interactive Multimedia messaging return channel protocol over satellite (based on Enhanced Spread Spectrum Aloha) has been developed and tested under real environment conditions within the framework of SafeTRIP, an FP7 EU-funded project. This paper presents the first field… (More)
The combined automatic repeat request and rate control mechanism in S-band mobile interactive multimedia asynchronous return link— design background, parameter dimensioning and first experimental results SUMMARY In the S-band mobile interactive multimedia specification, an asynchronous access using Enhanced Spread Spectrum Aloha random access has been… (More)
Herein, the results of the ESA co-funded research project named " ORTIGIA " are summarized. The scope of the project was to validate experimentally the techniques introduced by the DVB-SH working group to counteract fading in satellite and terrestrial environments. The experiments include measurements both on the field and in the laboratory.
