ELaNa-­‐12  ODAR     ARC1  –  UAF  –  1U       The  Alaska  Research  CubeSat  1  (ARC1)  will  be  the  first  satellite  designed,  built,   tested,  and  operated  by  students  from  the  University  of  Alaska  Fairbanks  (UAF).   This  satellite  is  designed  as  both  an  educational  tool  and  a  platform  to  facilitate   rapid  development  of  scientific  and  technology  demonstration  missions  at  UAF.   Successful  implementation  of  this  development  platform  will  demonstrate  the   ability  of  UAF  students  to  compete  for  future  Low  Earth  Orbit  (LEO)  research   opportunities.  ARC1  will  achieve  one  educational  mission  objective  (EMO)  and  three   science  mission  objectives  (SMO)  which  serve  to  demonstrate  what  capabilities  are   available  for  future  missions,  and  identify  unforeseen  system  issues  to  be  improved.     • EMO1:     Provide   an   authentic,   interdisciplinary,   hands-­‐on   student   experiences   in   science  and  engineering  through  the  design,  development,  operation  of  a   student  small  satellite  mission.     • SMO1:     Characterize  thermal  and  vibration  environment  inside  the  launch  vehicle   from  ignition  to  orbit  insertion.     • SMO2:     Validate  a  novel  low  power  Attitude  Control  and  Determination  Systems   (ACDS).     • SMO3:   Validate   a   high   bandwidth   communication   system   by   obtaining   images   of   changing  snow/ice  coverage  in  arctic  region.          

CONOPS:     Upon  deployment  from  the  P-­‐POD,  ARC1  will  power  up  and  start  counting  down   timers.  At  45  minutes,  the  antenna  will  be  deployed  and  the  beacon  will  start   transmitting.    Once  contact  has  been  established  with  ARC1  then  the  LEDL  and  ADCS   data  can  be  downloaded  to  complete  the  primary  mission.  Once  the  primary  mission   is  complete  the  camera  will  be  activated  to  take  pictures  of  the  arctic.  This  will   continue  until  ARC1  is  shut  down  after  1  year.     Hazards:  There  are  no  pressure  vessels,  hazardous  or  exotic  materials.     Batteries:     There  are  two  power  systems  on  ARC1,  the  Clyde  EPS  and  the  LEDL  battery.  The   Clyde  EPS  uses  standard  Lithium  Ion  Polymer  cells  to  store  energy  from  the  solar   cells  and  power  ARC1  after  P-­‐POD  ejection.  The  Clyde  EPS  contains  over-­‐ charge/current  protection.  The  Clyde  EPS  cells  carry  the  UL  listing  number   MH13654.  The  LEDL  battery  uses  Lithium  Iorn  Disulfide  cells  and  powers  the  LEDL   during  launch  so  it  can  log  launch  data.  The  LEDL  battery  is  not  rechargeable  and  is   not  used  after  data  logging  is  complete.  The  LEDL  cells  carry  the  UL  listing  number     MH29980.  Overcurrent  protection  is  provided  for  the  LEDL  cells.
