EO-1 Launch Vehicle InterfaceIssues -Tip Off
Rates

• Baselined maximum tip-off of 3 degrees per second
• Initially achieved 3 deg/s by reducing separation
  spring rates
• Addition of Hyperion drives stowed C.G. further
  in the spacecraft -y direction, which is the
  major contribution to tip-off rates
• Preliminary Separation analysis indicate a
  nominal tip-off rate of approximately 4 deg/s,
  3s rate of 5 deg/s.
• Corrective action to be taken
• Verify Solar Array Deployable at 5 deg/s
• Verify detumble capability of ACS with initial
  rate of 5 deg/s
