  16. DWSS Overview • Contract Facts • DoD Contract for Space Segment • Northrop Grumman (NGAS) prime integrator • NGAS modified C-bus • Sensor Subcontractors • Raytheon El Segundo (VIIRS) • Microwave Sensor – under development • JHU/APL (SEM-N) • NOAA/NASA for Ground System • Common Ground System (CGS) shared with NPP, JPSS, and international partners DMSP • DWSS Mission Description • Provide early morning polar orbital plane data for weather mission based on NPOESS IORD II as modified by JROCM 101-06 • Program Status • 13 Aug 11 – Acquisition Decision Memorandum approved for DWSS program • NGAS provide 2 spacecraft w/VIIRS, SEM-N, and Microwave Sensor • FY Funding and contract restructure in progress • Memorandum of Agreement in draft for CGS • DWSS F1 scheduled to launch in 2018 • DWSS F2 scheduled to launch in 2021

  17. VIIRS Overview • Advanced modular multi-channel imager radiometer • DWSS Primary sensor, supports 23 EDRs • Heritage OLS, AVHRR/3, MODIS & SeaWiFSsensors • Continuous Cross-track scanner • 22 spectral bands • Data Products • Atmospheric, clouds, earth radiation • Clear-air land/water surfaces, sea surface temperature, ocean color, and low-light visible imagery • Supplier: Raytheon Space and Airborne Systems, El Segundo CA

  18. Proposed Microwave Sensor • Collects global microwave radiometry & sounding data • Produces microwave imagery and other meteorological and oceanographic data • Conically-scanning passive microwave sensor supporting EDRs • Provides critical weather information, such as soil moisture, sea surface temp & wind direction capabilities Deployed Configuration Microwave 3-D view - water vapor, rain rate, vertical characteristics thru clouds

  19. SEM-N • Suite of particle sensors for the detection/measurement of the space environment • Measures energy spectrum and directional distribution of charged particle fluxes near the spacecraft • Comprised of 3 sensors • Special Sensor J5 (SSJ5) for detection of low-energy particles • Energetic Particle Spectrometer (EPS) for medium-energy particles • Omni-directional detectors for high-energy particles • Sensor suite integrated by Johns Hopkins University/Applied Physics Laboratory (JHU/APL) • Provided as GFE to NGAS for integration

  20. DWSD at McMurdo

  21. DWSS Overview • Contract Facts • Harris - DMSP Equipment • Raytheon - Antennas and JPSS Equipment • Raytheon Polar Services – Logistics • NSF – touch labor maintainance DMSP • Program Status • Raytheon completed Antenna build during 2010 – 2011 season • Harris successfully completed Critical Design Review • Season kickoff meeting scheduled for 13 Apr 11 • Testing planned for Mid-December 2011 • IOC of DMSP planned for Jan 2012 • McMurdo will be available for JPSS as part of CGS State 2 • McMurdo Mission • To incrementally reduce DMSP stored mission data latency, SPO identified McMurdo as ideal southern hemisphere readout site (latency goal is 15 minutes as opposed to 101 minutes max today) • Dramatic increase in DMSP fine resolution OLS cloud imagery data from 35% /rev to ~100% /rev global coverage • McMurdo Station – Ross Island • 77.5°S (similar in Latitude to Svalbard) • 166.6°E (below Australia/New Zealand)

  22. Current Latency

  23. Latency After McMurdo is Online

  24. Architecture Layout McMurdo Project spans Legacy DMSP and JPSS Common Ground System

  25. Conclusion • DMSP is the Military Weather flagship and will be for years to come • DWSS will continue the 40+ year legacy of DMSP • McMurdo will cut latency of DMSP by almost half and is a key site for JPSS and DWSS
