Overview of DVB-RCS+M and its development

The use of DVB-S and DVB-RCS for conducting two-way communications from small satellite terminals has become well established in Europe and elsewhere. During the development of DVB-RCS the possibility of limited use for satellite terminals that were moving was considered in January 2004 and incorporated into the Guideline document associated with the Standard in April 2005. It was noted, however, that this matter be addressed further as a future development. This paper addresses the steps that have been taken since then to realise this objective. During the last few years, it has been shown that the DVB-S2/DVB-RCS specifications are good candidate baselines for the efficient implementation of broadband services to mobile users. Results of these studies were gathered in a study mission report from the TM-RCS adhoc group. It was demonstrated that both forward and return channels waveforms are impacted by the mobile usage, and should be addressed in the scope of a update of the DVBRCS standard.
