leak problem prevented spacecraft from going into
Storage as planned. Repair dependant on
refurbishment of thrusters by Valve-Tech and
return of instruments being repaired in Europe.

Future 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 (IT).
• 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 IT 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.

Future Polar Satellite Status

• 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.

Future Polar Satellite Status

• 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.
