1. Raytheon Polar Services Company UNITED STATES ANTARCTIC PROGRAM McMurdo Ground Station Workshop Columbus, OH USAP Terascan Satellite Data Systems Overview Prepared by Andy Archer Presented by Kathie Hill 9 March 2004 Raytheon Polar Services Company

2. Advancing Polar Science Raytheon Polar Services Company USAP Antarctic Ground Stations RPSC maintains three fully operational satellite ground stations that routinely collect DMSP, NOAA and SeaWiFS satellite data. These data are processed real time and archived to tape for later access by researchers and planners. There are a host of imagery products produced and used daily by operations and science for the Antarctic program.

3. Advancing Polar Science Raytheon Polar Services Company McMurdo Region RPSC runs two L and S band ground station systems at McMurdo station. These ground stations capture and process approximately 35 DMSP and NOAA passes every 24- hour period per system. The SeaWiFS data is collected at a frequency of about 6 passes per day. All data is saved to tape and sent to the Scripps institute with exception of SeaWiFS data, which is electronically transferred near real time to the NASA archive

4. Advancing Polar Science Raytheon Polar Services Company Palmer Peninsula Region RPSC runs one L and S band ground station at Palmer Station taking in approximately 30 DMSP, NOAA, and SeaWiFS passes per day. All data is saved to tape and sent to the respective archive sites. The Palmer station ground station is in a unique region to provide sea ice extents for the Palmer Peninsula and Weddell Sea areas

5. Advancing Polar Science Raytheon Polar Services Company Antarctic Research Vessels RPSC maintains a single L and S band Terascan system, also collecting DMSP, NOAA, and SeaWiFS data. The regions of study are typically the Ross Sea and Antarctic Peninsula area. Data are collected whenever the RVIB NBP is operating below 55 degrees south. All data is saved and sent to the archive sites.

7. Advancing Polar Science Raytheon Polar Services Company Future Efforts RPSC will continue to maintain L and S band equipment as long as the requirement is in place. There will be some changes to the computers and antenna’s at USAP Terascan sites. Changes include migrating to a Linux operating system, increasing the physical size of receiving antennas to 1.5 meters and changing receiver models The operation and image product delivery will remain mostly the same. Image product development will remain flexible to accommodate science support and operational requests or each season.

8. Advancing Polar Science Raytheon Polar Services Company X-band RPSC is prepared to implement a real time X-band imagery processing environment upon request by the National Science Foundation. X-band data request capability through NASA: MODIS data is available now through The Ocean color web, RPSC will be prepared to assist with this utility as requested by interested science parties. http://oceancolor.gsfc.nasa.gov/
