RELATED ACTIVITIES: The epace segment of the Fleet Satellite Communications System 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 Air Force Satellite Communications Systen packages on Fleet Satellite Communications and Satellite Data System satellites are funded within the Air Force Satellite Communications System Program Element, 33601F. Terminals installed in aircraft were funded in the specific weapons system/aircraft Program Element. The Air Force Satellite Control Facility network is funded under Program Element, 35110F. C ] Space Shuttle flights for the Satellite Data System satellites are provided by the Space Launch Support Program, Program Element, 35171F. MILSTAR, a new highly jam-resistant satellite .4i8 being developed under Program Element, 33603F. 6. (U) WORK PERFORMED BY: Air Force Systems Command's Space Division, Los Angeles, CA, is responsible for the Satellite Data System. The primo contractor is Hughes Aircraft Company, El Segundo, CA. General Systems Engineering and Integration {s performed by the Aerospace Corporation, El Segundo, CA. 7.

Budget Activity: Strategic Programs, #3 Program Element: #35158F, Satellite Data System Test and Evaluation Data l. Development Test and Evaluation: The development contractor for the Satellite Data System was Hughes Aircraft Company, El Segundo, California. The first satellite was launched in Initial Operational Capability was established in The first satellite (F-1) 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 comaunication subsystems, a structural model spacecraft (X-1) and a qualification model spacecraft (Y¥-1). Development tests of the communications subsystems engineering modela were completed in November 1973. Structural testing was satisfactorily completed on the X-1 engineering mcdel spacecraft in May 1975. Systems level qualification was completed in October 1975 with all critical performance specifications met or exceeded. System level qual{fication waa designed to demonstrate design integrity and performance to specification via a series of tests including shock, acoustic, modal survey, thermal, electromagnetic interference, olar-theraal vacuum, and integrated system test. The F-1 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). 2. (U) Operational Test and Evaluation: A portion of the Satellite Data System is to be part cf the Air Force Satellite Communications space segment. Claseicai separate Initial Operational Test and Evaluation was not conducted on the space segments since all operational cbjectives 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 follow-on test and evaluation which is managed by the Air Force Test and Evaluation. Center. Resulta to date are contained in Development Test and Evaluation reports (see paragraph 1 sbove). 3.
