[Isocops] Hawaii 21 March 1710

[Reno, Michelle]

Ryan, Bret - 
 
The number of pulses cited here are very different than the expected values for the maneuver I cited in the checklist. I got my numbers from the monthly trending. What are reasonable ranges to expect for a sun pointing maneuver due to an outage at perigee (~8.5 degree maneuver)? 
 
Can you explain what we should be looking for in the thruster pulses to verify the maneuver magnitude roughly? In an earlier email it was designated that 1&2 were a pair and 3&4 were a pair, but 2&3 have the same number of pulses as do 1&4. Are we looking for the total number of pulses, or the difference between the number of pulses in each pair?
 
Thanks,
Chelle

All,
   The Hawaii support was failed due to a poor signal quality.  The Eb/No
ranged from 1 to 17 db. Spacecraft looked nominal and the maneuver was
successful.
Eb/No: @ 1710  2k    3 to 14 db
               @ 1715  2k    1 to 17 db
               @  1732 2k    1 to 12 db
USN PR 10,000
Razor Issue I100-450   Intermittent data Hawaii 21 Mar 11 1710
