DMSP Constellation Status 1

DMSP Constellation Status 2

• F15 Attitude Control
• Precision attitude control provided by 3 gyros
• One failed in Sep 01 second showing signs of
  failure within months
• Failure of second attitude gyro would introduce
  earth-location errors up to 30km in F15 data
• F12 and F14 have only a few months' life left on
  last remaining digital tape recorders
• F13, despite age, remains healthy

DMSP F16 Latest Developments

• DMSP flies in early-morning (F13) and mid-morning
  (F12, F14, F15) orbits
• F16 slated for early-morning orbit F17 for
  mid-morning
• F15 attitude control problem now makes
  mid-morning orbit more likely to lose all
  operational spacecraft than early-morning orbit
• AFWA requested F16 orbit change to mid-morning
• DMSP CSAT concurred
• Launch currently scheduled for 29 Jan 01
• F16 has same gyros as F15 SMC and NOAA SOCC
  studying gyro failure mitigation strategies
• F13 likely to fail before replacement by F17 in
  early '04 user community and AFSPC need to
  advocate for funding of other launch options if
  F17 needed sooner

AFWA SPP Product Transition Status 1

• DMSP Mission Sensor Data Files
• Legacy prep files still produced for F12-F15
  will discontinue when no longer needed but NLT
  May 02 (mainframe decommissioning)
• New Raw Sensor Data Record (RSDR) files
  operational now for F12-F15
• Only RSDRs will be produced for F16

7
AFWA SPP Product Transition Status 2

• Snow Depth Analysis
• Legacy format product (SNODEP) will remain
  operational NLT mainframe decommissioning in May
  02
• Interface specs and sample files in new GRIB
  format have been sent AFWA resolving format
  problems with FNMOC and NESDIS
• New product will be operational as soon as
  problems resolved

8
AFWA SPP Product Transition Status 3

• Cloud Analysis
• Legacy format product (RTNEPH) will remain
  operational NLT mainframe decommissioning in May
  02
• Interface specs have been sent coordinating
  additional changes now based on feedback
• Sample files with higher resolution and in new
  GRIB format will be sent by mid-Dec 01
• New product will be operational when AFWA CDFS II
  system becomes operational in May-Jul 02

NPOESS Centrals TIM

• Centrals found similarities among present-day
  satellite and projected NPOESS data consumption
  patterns
• Centrals agreed that NPOESS IDPS should provide
  data management services
• Would reduce data latency incurred by data
  receipt, processing, storage, and retrieval at
  the Central
• Would spare Centrals the expense of duplicating
  services the IDPS will likely require for its own
  use
• Centrals urged IPO to seek type-accreditation for
  IDPS to lessen security difficulties

10
Geostationary Feature Track Winds Status

• AFWA Meteosat-5, Meteosat-7, and GMS-5 feature
  track wind production considered operational by
  AFWA and FNMOC/NRL
• AFWA providing sample GOES data to NRL/UW for
  GOES "McIDAS-independent" FTW algorithm
  development

11
EOS Data Acquisition

• AFWA views EOS data, particularly from MODIS, as
  NPOESS risk reduction
• Working with NASA/Goddard and NOAA/NESDIS to
  receive operational MODIS products
• GSFC Rapid Response server and DREN initially
• NOAA EOS server and possibly SPN end-state
• Initial product request for limited set of MODIS
  Level-1B and 2 products over Afghanistan AOR
• Will grow product request to include more MODIS
  data as experience and capability grows will add
  sounder instruments later

12
Updated INSAT Requirements

• Currently receiving only INSAT-1D imager data
• Poor earth-location and 1-1.5 hours latency
  limits utility
• Request NESDIS investigate obtaining
• INSAT-2E CCD data
• Imager and CCD data from INSAT-3 series and
  following launches
• Specs for INSAT direct-readout data
• More frequent than 3-hourly imagery when
  available
• Timeliness and reliability improvement
• Earth-location algorithm for INSAT-1D
