Background. On December 7, 2016, the US Air Force launched the 8th of 10 planned Wideband Global SATCOM (WGS) satellites into orbit, from Cape Canaveral in Florida. This latest WGS satellite marks a technological leap forward for the WGS constellation, bringing more X- (and Ka-band) capacity to the Department of Defense. X-band is also an important part of NATO’s own CP130 capabilities package for satellite communications. There is a reason that the Department of Defense and NATO have invested so heavily in X-band: X-band provides high-throughput, virtually weatherproof satellite communications that excels with high-mobility, lightweight applications ranging from forward tactical and SOF units, to maritime communications, to airborne ISR and UAV assets. For these types of applications, X-band in fact provides substantially better service than Ka-band. No wonder X-band is a key component of the Department of Defense’s and NATO’s SATCOM architectures.
