1	CORS Network FY2007 Giovanni Sella CORS Program Manager NOAA- National Geodetic Survey giovanni.sella @ noaa.gov CORS Users Forum at the CGSIC Meeting Fort Worth, TX September 25, 2007
2	CORS = Partners CORS is > 98% volunteer
3	CORS Network in CONUS 2007
4	Volume of Online CORS Data Stored
5	CORS Monthly Data Downloads 2002-2007
6	Access to CORS data In Silver Spring (CORS-East) Anonymous FTP cors.ngs.noaa.gov UFCORS- User Friendly CORS www.ngs.noaa.gov/UFCORS In Boulder Colorado (CORS-West) Parallel and independent data collection and on-line storage at NGDC (National Geophysical Data Center) Anonymous FTP wwwest.ngs.noaa.gov Future: Add OPUS and UFCORS
7	CORS Activities FY 2007 OPUS showcased as e-gov initiative by Department of Commerce OPUS-RS operational product (allows users to submit 15 min) NGS GPS orbits reach 1 cm-level NGS was selected to the IGS Analysis Center Coordinator (4 year term). Coordinate IGS orbit products. HTDP software for the western US has almost been revised Continued to prepare for complete re-analysis of all CORS data including all orbits 1994-to date ~1.5 Tbyte of data. CORS-West fully operational Prototype CORS-Realtime service almost operational
8	OPUS Usage and Users
9	What have our partners been doing? Upgrading stations, phasing out equipment that is past end-of-life = improving overall network quality Upgrading stations to GNSS i.e. GLONASS, L2C NGS will archive this data Establishing new stations and aggressively moving to realtime USCG/NDGPS have upgraded ~40 sites
10	Proposing New CORS During FY 2007 very few new CORS accepted WHY? A host of internal software/hardware and network problems Started working this month on a backlog of ~400 CORS We expect most of the sites to be accepted so CORS will expand significantly Guidelines very important www.ngs.noaa.gov/CORS/Establish_Operate_CORS.html ngs.proposed.cors @ noaa.gov
11	Supported International Activities Assisting in establishing a 7 station CORS network in Benin at the request of the Millennium Challenge Corporation of the US State Department and in collaboration with UNAVCO Establishing 3 CORS stations in Ethiopia to support a USAID project on land privatization Establishing 1 station in the British Virgin Islands
12	NOAA’s US-TEC Space Weather Program Became an operational product in FY 2007 Uses CORS data to calculate total electron content (TEC) in the ionosphere. Needed for space weather e.g. airplanes, telecommunications
13	NOAA’s GPS Meteorological Program Provides a tropospheric model of wet zenith delay over the US. It currently is one of the input data sets for the National Weather Service forecasting models. Will transition from research to operations in FY 2009
14	Plans for FY 2008 New OPUS flavours (more in a little bit) Start of re-analysis of all CORS data and orbits (2 years) Guidelines for realtime GPS (more in a little bit) Publish new HTDP for Western US Start work on new HTDP for Alaska Continue to work with our partners to improve existing stations and add new ones
15	Questions For any questions that you have on or about CORS products and services do contact NGS staff. If you don’t know who to contact start with me and I’ll put you in contact with the appropriate person. Giovanni Sella giovanni.sella @ noaa.gov
