Introduction special issue on DVB-RCS+M

摘要

DVB-RCS is really the first and only broadband satellite communications standard. With work started already in 1998 and the first version approved in the DVB project already in 1999-10 years ago-we are already talking of a mature technical specification. At the time the focus was on ATM to the desktop, Ka-band systems and large low-earth-orbit satellite constellations; or at least a lot of the community interest; and systems were proposed with several hundred satellites. In ETSI there were two alternative specifications published at the time for mobile satellite services based on GSM; these were the so-called GMR-1 and GMR-2 specification-both basically connected to one system each and one (or a few) vendors each.
