[Isocops] Command Approval Checklist Rev 8

Mon Jan 23 10:14:14 EST 2012

I do have a couple comments. I don't mind a few more rules. I think we 
need to discuss the rules a little more. 
Contacts - How long should we wait until we schedule a contact pre & post 
eclipse?
Maneuvers - Should there be a minimum time Pre or Post eclipse before we 
plan the maneuver? 
Science collection - What steps should we take for the instrument? 
 Just a couple thoughts.

Hi All,

Attached is Rev 8 of the command approval checklist. It has been modified

Contact Commands
·         Each contact has 5 commands
1.     Verify STX on/off times, downlink rate against Orbit_oXXX.txt file
2.     Verify contacts in the previous ATS have not been duplicated 
3.     Verify all currently planned contacts in Orbit_xxx.txt are in the 
ATS.
4.     Verify each contact contains the following 5 commands
·         SetRelay stx,on 
·         SetDownlink2K  (2K, 40K, 64K, 160K, or 320K)
·         SetBilevelOutputControlReg STXMODE_Strobe,ON 
·         SetBilevelOutputControlReg COHERENT,ON 
·         SetRelay stx,off 
5.        Verify contact is not during an eclipse.
6.        If an APL contact is being used for an SSR Dump, the data rate 
should be at least 160 ksps & the SSR Dump New command should be included 
in the contact commands : 
·         SetRelay stx,on
·         SetDownlink160K
·         SetBilevelOutputControlReg STXMODE_Strobe,ON
·         SetBilevelOutputControlReg COHERENT,ON

Eclipse Check
1.     Check OEF for eclipses during the orbit.
2.     Verify no contacts planned during an eclipse.
3.     Verify no maneuver planned during an eclipse.
This applies to all eclipses, not just moderate or long eclipses.
