Abstract: ABSTRACT The DVB project has been active in maintaining and adapting its specifications to the requirements of modern satellite communications systems. The physical layer specifications, which include DVB‐S2X for the forward link and DVB‐RCS2 for the return link, have been recently updated to support beam hopping over the forward link and signaling within a VSAT system, including some support of nongeostationary orbit (NGSO) satellites. Last year, the DVB Commercial Module issued a new set of requirements for further support of NGSO by the DVB‐RCS2 standard. The requirements call for support and analysis of operation within an NGSO system and extending the capabilities of the return link to support higher capacity and enable more symmetric traffic. The DVB Technical Module (satellite working group, TM‐S) has produced an enhancement of the specifications and performed a set of analyses to answer the commercial requirements. In the paper, the new features described above will be introduced, as well as the analyses and discussions.
