**May 2003 Polar Satellite Status**

## NOAA-N Status:
Spacecraft having Reaction Control System partially refurbished due to “leaking” thrusters.
First ‘End-to-End” test with NOAA SOCC scheduled for Fall 2003.
DCS instrument had “spacecraft fuse blow” during spacecraft Integration & Test (I&T).
Extensive research effort conducted by CNES/Thales/CMAC found intermittent spurious oscillation during instrument turn on/warm up period.
Modified oscillator circuit with suppression capacitor
Instrument returned to LMSS in Jan 2003 and integrated onto spacecraft without incident
SARP instrument slated for NOAA N uses same oscillator. Instrument was refurbished and returned to LMSS in June 2003.

**Future Polar Satellite Status**

## NOAA-N Status (Cont.):
Battery production difficulties by Saft (France) has delayed delivery of flight batteries:
Current battery delivery schedule has flight batteries delivered to LMSS in Feb 2004.
Use of DMSP S-17 batteries may be necessary. Retrofit of SARP oscillator planned after S/C goes to storage.
An extensive investigation into on-orbit anomalies with the S-band transmitters may require transmitter re-design and cause launch delay.

**Future Polar Satellite Status**

**NOAA-N’ Status:**
- Spacecraft is completing Thermal Vacuum testing in June 2003.
- Some issues have arisen with regards to message processing at low signal levels.
- Special testing at end of TV testing with CNES support.
-  CNES already at LMSS to support NOAA N SARP/2 delivery and bench acceptance testing.
- A-DCS and SARP/3 were tested successfully during integration with minor processing errors being evaluated.
- LMSS I&T ground system (ATNAGE) required extensive modification for A-DCS and SARP/3 telemetry and command processing.
- Late delivery did not allow time to “flush out” all errors previously.
- CNES/Thales evaluation of pre-TV data agreed instrument performance was nominal.

**NOAA-N’ Status (cont.):**
- Issue with A-DCS transmitter found (box level qualification testing) during instrument start-up at temperatures outside specification exists.
- Some concern that signature could “shift” over time to a temperature within the performance specification.
- CNES requires instrument return to evaluate “root cause” and repair.
- Spacecraft Electro-Magnetic Interference (EMI) testing will be delayed until after the launch of NOAA N (June 2004).
- Current LMSS contract expires in April 2004. Extension of contract being negotiated to include yearly testing of spacecraft.

## Future Polar Satellite Status

- MetOp
- First satellite scheduled for launch in 2005
- Will fly US-provided instruments and the A-DCS & SARP/3 provided by CNES.
- Joint Technical Agreement (JTA) slated to be signed in summer 2003 stating that spare US instruments will be provided to Eumetsat to “fly” on MetOp3 in 2014.

## NPOESS Status
Integrated Program Office (IPO) manages NPOESS program.
Spacecraft contractor selected (TRW Inc.) in August 2002.
Interface Control Document (ICD) for A-DCS has been defined using modified POES ICD.
