After the earlier technologies that offered satellite mobile services for civil and military applications, today’s specific antenna design, modulation techniques and most powerful new generation satellites also allow a good level of performance to be achieved onboard high speed modes of transport such as aircraft and trains. This paper reports the(More)
Eutelsat plays key role in the provision of mobile services over geosynchronous satellites. Starting with narrowband services for land transports, through broadband maritime service until the most recent IP and multimedia services on board high speed means of transport (trains and airplanes), Eutelsat is present in this market for several years, as services(More)
This paper analyzes part of the results of the tests done on a DVB-S2 link received on board a high speed train. The tests aimed at verifying the behavior of the DVB-S2 in the railway environment, which introduce line of sight (LOS) interruptions and variable fading, when different modcods and types of traffic are transmitted. Mainly, MPEG2 Transport Stream(More)
The new generation multi-spot Ka band satellites increase dramatically the offer of capacity whose cost is consequently reduced and give promising perspectives for fix interactive broadband services and mobile services. However, if on one hand the market and deployment of fix interactive broadband services definitely benefit from Ka band, on the other hand(More)
