AS PART OF THIS EXPANSION, THE SBN/NOAAPORT SIGNAL WILL BE TRANSITIONED FROM THE CURRENT DVB-S STANDARD TO A MORE EFFICIENT DVB-S2 STANDARD. TODAY, THE NWS AWIPS PROGRAM AGREED TO A DELAY OF 45 DAYS TO ALLOW MORE TIME FOR THE NOAAPORT COMMUNITY TO PREPARE FOR THE TRANSITION. THE AWIPS PROGRAM HAS SELECTED A DVB-S2 RECEIVER FOR THE SBN/NOAAPORT EXPANSION PROJECT. WE WILL BE IMPLEMENTING A SINGLE DATA STREAM THAT WILL REQUIRE VARIABLE CODING MODULATION -VCM- OVER MULTI-PROTOCOL ENCAPSULATION -MPE- WHICH IS SUPPORTED BY OUR SELECTED RECEIVER. WE UNDERSTAND THAT ONE OR MORE OTHER MODELS OF DVB-S2 RECEIVERS MAY ALSO BE SUITABLE. THE RECEIVER SPECIFICATIONS CAN BE FOUND ON THE NOAAPORT WEB SITE. TECHNICAL SPECIFICATIONS FOR THIS PROJECT ARE BEING FINALIZED AND WILL BE MADE AVAILABLE VIA THE NOAAPORT WEB PAGE AS THEY ARE COMPLETED. IN PREPARATION FOR THE TRANSITION, THE NWS WILL BE PROVIDING A 30 DAY WINDOW STARTING APRIL 18 2011 UNTIL MAY 17 2011 OF DUAL ILLUMINATION WITH BOTH THE -DVB S- AND -DVB S2- STANDARDS TO ALLOW AWIPS SITES AND NOAAPORT CUSTOMERS TIME TO FINALIZE THEIR TRANSITION.
