Migration of DOD Satellite Operations from the Space Ground Link Subsystem Frequency Band to the Unified S-Band. Transponder Specifications for Small Satellites.

Migration of DOD Satellite Operations from the Space Ground Link Subsystem Frequency Band to the Unified S-Band. Transponder Specifications for Small Satellites.

Since the beginning of satellite operations in the 60’s, the Department of Defense (DOD) has enjoyed exclusive use of the Space Ground Link Subsystem (SGLS) band (1755-1850 MHz) for satellite operations. Growing pressure from 3rd generation mobile wireless devices for use of the SGLS band, as well as the need for the DOD to be interoperable with the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Admin istration is making it necessary for the DOD to re -evaluate the exclusive use of the SGLS band and a possible additional use of the Unified S-Band (2025-2110 MHz). Included will be an implementation plan for the migration of DOD satellite operations and the possible impacts on small DOD satellites. Included will be a discussion on the Air Force Satellite Control Network modification timetable and a discussion on development of a dual band transponder for operation in both bands.
