Test  and  Evaluation  Data 
1.  Development  Teat  and  Evaluation:  The  development  contractor  for  the  Satellite  Data  System  was 
Hughes  Aircraft  Company,  El  Segundo,  California.  The  first  satellite  was  launched  inF 
J  Initial  Operational  Capability  was  established  in£  ]  The  first  satellite  (F-l) 
waa  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-l)  and  a  qualification  model  spacecraft  (Y-l).  Development 
tests  of  the  communications  subsystems  engineering  models  were  completed  in  November  1973.  Structural 
testing  was  satisfactorily  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  qual If fration  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-l  spacecraft  waa  acceptance  tested  during  the 
{_  J  The  Y-l  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  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  pay loads  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.   Results  to  date  are  contained  in  Development  Test  and  Evaluation  reports  (see  paragraph  1 
above).
