Version 1.5.1 adds support for NGSO constellations. The operational bandwidth of the return link was extended and lower roll-off waveforms were introduced. Major amendments included the addition of DVB-S2X waveforms on the return link, either within the TDMA grid or over a continuous carrier, replacing the former
continuous carrier waveform, which was deprecated.
The present document allows substantial configuration flexibility in that the burst constructions and FEC can be adapted to some extent to the operating environment of the RCST. In order to guide in implementation and interoperability a set of reference burst configurations are specified, and the essential configuration space for such configuration is also indicated.
