LEO	
  Mission	
  Description	
  
	
  




                                                                                                                   	
  
	
  
LEO	
  will	
  record	
  vibrational	
  and	
  thermal	
  measurements	
  with	
  two	
  accelerometers	
  
and	
  a	
  thermocouple	
  and	
  also	
  record	
  vibrational	
  data	
  taken	
  by	
  a	
  second	
  CubeSat	
  that	
  
will	
  be	
  transferred	
  through	
  WiFi	
  during	
  launch.	
  
	
  
Upon	
  deployment	
  from	
  the	
  P-­‐‑POD,	
  LEO	
  will	
  turn	
  off	
  its	
  WiFi	
  module	
  and	
  take	
  
pictures	
  of	
  the	
  StangSat	
  CubeSat	
  as	
  they	
  separate.	
  45	
  minutes	
  after	
  deployment	
  the	
  
antenna	
  will	
  be	
  deployed	
  and	
  the	
  UHF	
  beacon	
  will	
  be	
  activated.	
  For	
  the	
  first	
  few	
  
passes	
  the	
  ground	
  station	
  operators	
  will	
  attempt	
  communications	
  to	
  perform	
  
checkouts	
  of	
  the	
  spacecraft.	
  Data	
  from	
  the	
  requested	
  EOIs	
  will	
  then	
  be	
  able	
  to	
  be	
  
downlinked.	
  
	
  
After	
  the	
  data	
  is	
  successfully	
  received	
  at	
  the	
  ground	
  station,	
  LEO	
  will	
  continue	
  to	
  
operate	
  throughout	
  the	
  orbital	
  life	
  (approx	
  2.9	
  years)	
  as	
  a	
  digipeater	
  for	
  HAM	
  
operators	
  who	
  will	
  have	
  access	
  to	
  telemetry	
  data	
  from	
  the	
  LEO	
  beacons.	
  
	
  
The	
  CubeSat	
  structure	
  is	
  made	
  of	
  Aluminum	
  6061-­‐‑T6.	
  It	
  contains	
  all	
  standard	
  
commercial	
  off	
  the	
  shelf	
  (COTS)	
  materials,	
  electrical	
  components,	
  PCBs	
  and	
  solar	
  
cells.	
  
	
  


There	
  are	
  no	
  pressure	
  vessels,	
  hazardous	
  or	
  exotic	
  materials.	
  
	
  
The	
  electrical	
  power	
  storage	
  system	
  consists	
  of	
  common	
  lithium-­‐‑ion	
  batteries	
  with	
  
over-­‐‑charge/current	
  protection	
  circuitry.
