Description: The US military requires a reliable, high-speed, multimedia capable system to disseminate information that      cannot be efficiently distributed over existing low data rate channels. The Global Broadcast Service (GBS) is      being developed to meet this requirement. The cornerstones of the OBS simplex broadcast are the premises      of smart push and user pull. An integral part of the user pull is the reach back channel. The reach back      channel allows users to speciiy the information they need broadcast and tailor the information to meet their      mission needs. Ultra high frequency (UHF) demand assigned multiple access (DAMA) satellite      communications are the most widely available long haul communication systems available to members of the      armed services and as such are a prime candidate to provide a reach back path for GES. In order to fully      utilize UHF DAMA as a reach back channel for data communications a number of interface requirements      must be met. The problems of using UHF DAMA are discussed and recommendations are made for the      OBS Phase Two systems so they might support the use of UHF DAMA as a reach back channel. This thesis      shows that UHF DAMA is a viable reach back channel, however there are factors which could improve the      efficiency.
