The Wideband Global System (WGS) is currently operational in the Pacific Ocean using WGS1 (175E). GBS traffic is supported in that theater today using the Digital Video Broadcast by Satellite (DVB-S) and operates using terminals originally designed for operation using the UHF Follow-On satellite (UFO8). These terminals can now operate over WGS1 and UFO8. GBS is planned to migrate to the JIPM in 2010. The Joint IP Modem (JIPM) will use the second generation DVB-S2 which represents a quantum leap in capability over DVB-S in terms of its power and bandwidth efficiency. Further the JIPM allows hub-spoke operation between a control center at a Teleport and the remote terminals equipped with a remote Modem.
