Program Element: ; unications, #333 Budget Activity: Strategic Programs, #3 #35L58F Title: Satellite Data System DoD Mission Area: Strategic Comm : (V} DETALLED BACKGROUND AND DESCRIPTION: The Satellite Data System provides critical real- time command, control, and communications for Strategic Air Command Single Integrated Operationai Plan and other nuclear capable forces. It is an {ntegral part of the Airc Force Satellite Communications System which alao Includee the Ultra Itigh Frequency communtcations capability on the geosynchronous Fleet Satellite Communications satellites, pigay-back transponders on selected host sateliftes, and airborne/ground rad{o terminally. As such, the Satellite Data Systea complements the Fleet Satellite Communications coverage by providing polar coverage which the other _, satellites cannot provide. Additfonally, the Satellite Data System supports the Air Force Satellite Control Facility requirement for reifable, two-way high data rate communications with {ts remote tracking stations. ( The direct benefits of the Satellite Data System are relfable and secure direct communications which will result {n greatly improved command and control of our nuclear capable forces, fliaination of the dependence on some of the vulnerable Airc Force Satellite Control Faciiity communications, (Up RELATED ACTIVITIES: The space segment of the Fleet Satellite Communications Syste was developed, procured, and launched under the Navy's Program Element, 33109N. The Air Force ground Ultra High Frequency radio terminals needed for operation with the Fleet Satellite Communications and Satellite Data Systea satellites are funded within che Air Force Satellite Communications Systes Program Element, 33601F. Terminals installed in sircraft were funded in the specific weapons system/aircraft Program Element. The Airc Force Satellite Control Facility network_is funded under Program Element, 35i10F. Space Shuttle flights for the Satellite Data System satellites are provided by the Space Launch Support Program, Program Element,, S5171F. MILSTAR, a new highly jam-resistant satellite is being developed under Program Element, 33603F.

FY 1981 and Prior Accomplishments: The technology. phase of the program was completed in FY 1971. This was followed by a contract definitfon phase tn FY 1972 which established the system configuration. The system scqui- gition contractor wags selected by compel{ttve source sele¢tion and a system development contract way awarded fn June 1972. The system Critical Design Review was successfully completed in March 1974 with all critical spectfications being met or exceeded. The structural model satellite testing was Finished {mn May 1975. A qualification model satellite was built and tested to fully qualify the satellite prior to production. All payloads were fully checked out on-orbit. Full operational capability waa declared for all payloads jafter successful on-orbit checkout. Primary activitles in FY 1981 included the continuatfon of design and development activities associated with improving the anti-jam capabilities of the Afr Force Satellite Communications System payload on the seventh satellite (F-6), the continuation of the multi-year development of a Space Shuttle optimized design on the seventh satellite, reliability {improvement efforts, and sustainlug engineering support. The production of the Fifth (F-5) and sixth (F-5A) satellites, to be launched on Titan/Agena, siso continued in FY 81. (yf 2. FY 1982 Program: Efforts for this year include sustaining engiacering support, continuing design and devel- opment activities to improve the unti-jam capabilities of the Airc Force Satellite Communications System payload oun the seventh Satellite Vata System gatellite, and continuing the multi-year development uecessury to transitflon Cthut Satellite to the Space Shuttle.

Budget Activity: Strategic Programs, #3 Program Element: T35158F, Satellite Data Systea 1. (V) Development Test and Evaluation: The development contractor for the Satellite Data System was tlughes Aircraft Company, El Segundo, Californta. The first satel!iite was launched f Initfal Operational Capability was established inf The first satellite (F-1) woe funded entircly within the development program. The second satellite (F-2Z) was the first vehicle funded under the production program. The development hardware inc luded engineering models of the communication subsystems, a structural model spacecraft (X-1) and a qualification model spacecraft (Y-1). Development tests of the communications subsystems engineering models were completed itn November 1973. Structural testing was satisfactortly completed on the -X-l engineering model spacecraft in May 1975. Systems level qualification was completed in October 1975 with all critical performance specifications met or exceeded. System level qualification was designed to dewonstrate design integrity and performance to specification via a serfes of tests including shock, acoustic, modal survey, thermal, electromagnetic interference, solac-thermal vacuum, and integrated system test. The F-l spacecraft was acceptance tested during the The Y-1 spacecraft was a fully configured spacecraft which has been refurbished and designated as Flight vehicle (F~4). A portion of the Satellite Data System is to be part cf the Air Force 2. (U) Operational Test and Evaluation: Satellite Communtcations space segment. Classical separate Initial Operational Test aud Evaluation was not conducted on the space segments since all operational objectives and requirements were fully integrated into the Deveiopment Test and Evaluation effort and were not broken out separately. Compatibility, operational characteristics, and orbit performance of payioads supporting the Air Force Satellite Communications program are scheduled to be demonstrated during the follow-on test and evaluation which is managed by the Air Force Test Results to date are contained in Development Test and Evaluation reports (see paragraph 1 and Evaluation Center. above). 3.
