Title: Satellite Data System Proqram Element #35156F Budget Activity: Strategic Programs, #3 DoN Mission Area: : Strategic Communications, #133 (0 DETALLED BACKGROUND AND DESCRIPTION: The SateLliite Data System provides critical, real- time command, control, and communications for Strategic Air Command Single Integrated Operational Plan and other nuclear capable forces. It {8 an integral part of the Air Force Satellite Communications System which also includes the Ultra High Frequency communications capability on the geosynchronous Fleet Satellite Communications satellites, piggy-back transponders on selected host satellites, and airborne/ground radio terminals. As such, the Satellite Data System complements the Fleet Satellite Communications coverage by providing the polar coverage which the other satetlites cannot provide. Additionally, the Satellite Data System supports the Air Force Satellite Control Facility requirement for reliable, two-way high data rate communications with its remote tracking stations. The direct benefits of the Satellite Data System are reliable and secure direct communications “which will result in greatly improved command and control of our nuciear capable forces, “elimination of the dependence on some of the vulnerable Air Force Satellite Control Facility communications, ~- (Dj RELATED ACTIVITIES: The space segment of the fleet Satellite Communications System was developed, procured, and launched under the Navy's Program Element, 33109N.

FY 1980 and Prior Accomplishments: The technclogy phase of the program was completed in FY 1971. This was followed by 4 contract definition phase in FY 1972 which established the system configuration. The system acqui- sition contractor was selected by competitive source selection and a system development contract was awarded in June 1972. The system Critical Design Review was successfully completed in March 1974 with all critical specifications being met or exceeded. The structural model satellite testing was finished in May 1975. fication model satellite was built and tested to fully qualify the satellite prior to production. All payloads were fully checked out after successful on-orbit A quali- on-orbit. Eyll operational capability was declared for ail payloads checkout. Primary activities in FY 1980 included the continuation of design and development activities assoctated with improving the anti-jam capabilities of the Air Force Satellite Communications System payload on the sixth and subsequent satellites, the continuation of the multi-year development of a Space Shuttle optimized design on the aixth and subsequent satellites, reliability improvemant efforts, and sustaining engineering support. {U) 2. FY 1981 Program: Efforts for this year include sustaining engineering support, continuing design and devel- opment activities to improve the anti-jam capabilities of the Air Force Satellite Communications System payload on the sixth Satellite Data System satellite, and continuing the multi-year development necessary to transition the sixth and subsequent satellites to the Space Shuttle. FY 1981 is the peak year for these development efforts, cul- minating in a Critical Design Review and qualification testing. Also included are continuing efforts to improve satellite payload reliabilities. {U) 3. FY 1982 Planned Program: Planned efforts include the continuation of the development efforts related to the Space Shuttle optimization and the completion of the development of the Air Force Satellite Communications payload anti-jam improvements. Sustaining engineering support and payload reifability improvements will also be continued.

Budget Activity: Strategic Programs, #3 __ Program Element: #35158F, Satellite Data System l. () Development Test and Evaluation: The development contractor for the Satellite Data System was Hughes Aircraft Company, Fl Segundo, California. The first satellite was launched ° a Initial Operational Capability was established in ~ The first satellite (F-1) ra was funded entirely within the development program. The second satellite (F-2) was the first vehicle funded under the production program. The development hardware included 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 in November 1973. Structural testing was satisfactorily completed on the X-1 engineering model spacecraft in May 1975. Systems level qualification was completed in October 1975 with sll critical performance specifications met or exceeded. System level qualification was designed to demonstrate design integrity and performance to specification via a series of tests including shock, acoustic, modal survey, thermal, electromagnetic interference, solar-thermal vacuum, and integrated system test. The F-1 spacecraft was acceptance tested during the . The Y-1 spacecraft was a fully configured spacecraft which ra has been refurbished and designated as flight vehicle (F-~4). 2. (U) Operational Test and Evaluation: A portion of the Satellite Data System is to be part of the Air Force Satellite Communications space segment. Classical separate initial Operational Test and Evaluation was not conducted on the space segments since all operational objectives and requirements were fully integrated into the Development Test and Evaluation effort and were not broken out separately. Compatibility, operational characteristics, and orbit performance of payloads supporting the Air Force Satellite Communications program are scheduled to be demonstrated during the fellow-on test and evaluation which is managed by the Air Force Test and Evaluation Center. Results to date are contained in Development Test and Evaluation reports (see paragraph 1 above). 3. 0) Systems Characteristics: Characteristics Objectives Demonstrated Data Rate in words per minute | Message Bit Error Rate { per ten thousand bits | { J Anti-Jam Protection (decibel watt) _ ~ 645
