## T/V Results 

***T/V Results ***

***All objectives met***
***S-Band Anomaly (Special Topic)***
***Additional demonstration of nominal operation of EO-1 Spacecraft and payloads at temperature extremes***
***Additional bake-out of ALI and Hyperion instruments***
***Conclusion***
***After S-Band replaced, EO-1 S/C qualified for on-orbit operation***
***Post Thermal Vacuum Functional Test was nearly flawless***

## Plan for Final CPT

***Plan for Final CPT***

***CPT following S-Band Re-integration at Vandenberg Air Force Base (VAFB)***
***Verify S-band performance in EO-1 system***
***Verify full EO-1 performance after shipment***
***Scheduled for September 2000***

## Additional Verification

***Additional Verification***

***Alignment***
***Final alignment measurement still planned for the launch site***
***Mass properties conducted just prior to shipment***
***Adjustment will be made for missing S-band***
***No existing issues***
***Electrical testing of deployables at S/C level still planned for the launch site***
***The remaining S/A deployment will be conducted with the flight fuse plugs installed, on the redundant side with no EGSE in the loop (at launch site).***
***The primary HOP path will be verified following the deployment to verify actuator motion with the flight fuse plugs.***
***Remaining testing planned will guarantee system functionality on-orbit***
