To meet the increasing need for additional wideband satellite capability within the Department of Defense, the Global Broadcast Service (GBS) is being developed. GBS is an asymmetric network providing up to 24 Mbps from the Satellite Broadcast Manager (SBM) to deployed forces via UHF Follow On (UFO) satellites during GBS Phase Two. The concept of Smart Push provides for most of the users' needs but cannot anticipate every need or emerging needs of the user. The user through User Pull requires the ability to request information products from the SBM through existing communication paths. This capability is termed reach back. Due to the nature of operations, not as much information is sent back from operating forces to headquarters commands; therefore, less bandwidth is required from deployed forces to headquarters commands. Reach back channels do not require as much bandwidth as GBS. This research explores the viability of using Satellite Tactical Digital Link J (S-TADIL J), also known as Satellite Link 16, as a reach back option for GBS.
