The Global Broadcast Service [GBS] augments and interfaces with other communications systems to provide a continuous, high-speed, one-way flow of high-volume information supporting routine operations, training and military exercises, special activities, crisis, situational awareness, weapons targeting, intelligence, and the transition to and conduct of operations short of nuclear war. The models are differentiated depending on the specific payload size and weight ranges. The primary contractor for the satellites themselves is Boeing Satellite Development Center, which is building them around the Boeing 702HP satellite bus. The system provides two-way X- and Ka-band communications, as well as Ka-band broadcast services to the US armed forces and other allied forces worldwide, and X-band satellite transfers of data, photos and videos to troops on the battlefield. In early 2001, a satellite communications industry team led by Boeing Satellite Systems was selected to develop the Wideband Gapfiller Satellite (WGS) system as successors to the DSCS-3 series of communications satellites. WGS also augments the current Ka-band Global Broadcast Service (on UHF F/O satellites) by providing additional information broadcast capabilities as well as providing new two-way capability on that band. Space Systems Command announced the milestone Feb. 1. Thus, each WGS can supply more than 10times the capacity of a DSCS-3 Service Life Enhancement Program (SLEP) satellite. Copyright 2023.
