IGS Analysis Center under the 8, provides ultra-fast (Ultra-rapidly), fast (Rapid) and final (Final) satellite orbits, clock and poor product (Product), to be applied to meet the global needs of research scientists and engineers, mainly analysis Center for the CDDIS (ftp://cddis.gsfc.nasa.gov), SOPAC (ftp://garner.ucsd.edu/), IGN (ftp://igs.ensg.ign.fr/), IGS_CB ( ftp://igscb.jpl.nasa.gov), KASI (ftp://nfs.kasi.re.kr/) and the like.
Since 1997, IGS stations ZPD products, each station every day a file, the file names of the form ssssddd0.yyzpd, where ssss is IGS station ID, ddd is the day of the year, yy was in. Download the installation file for the ftp://cddis.gsfc.nasa.gov/pub/gps/products/troposphere/zpd/, file directory structure in, day of the year is set, for example, in 2013 the first 200 days of ZPD products usno absolute path as ftp://cddis.gsfc.nasa.gov/pub/gps/products/troposphere/zpd/2013/200/usno2000.13zpd.gz.
Time resolution product ZPD 5 minutes, ZPD in millimeters (TROTOT- Total zenith path delay [mm]).

Let me talk GNSS observation data (data), there are currently providing several IGS / MGEX, US CORS, and Hong Kong CORS observation data download. Of course, the most used or IGS, is characterized by multi-site (more than 400), the global distribution; MGEX is a subproject of IGS for tracking multi-GNSS systems, the current number of sites has reached more than 100, is characterized by a global distribution and includes observations you may have heard of all kinds of satellite systems GPS, GLONASS, Galileo, Compass, QZSS, RNSS and so on. In addition several CORS system, the United States is available for download free CORS data, Hong Kong CORS data can also be downloaded for free, but registration is required.
As for the domestic provinces and cities CORS, Lu state network, iGMAS data, currently belong to at least z confidential, requires layers of approval, most people do not even think.
Besides precise ephemeris, precision clock and poor product (products), the major IGS Analysis Center (MIT, SIO, GFZ, etc.) will produce its own precision products. Products which central file abbreviated prefixes (e.g. sio18120.sp3), the final product IGS weighted average of all the analysis center to give the final product (IGS, IGR, IGU) prefix. IGS is currently only available products include GPS and GLONASS satellites.
MGEX as a sub-project of IGS, there are currently based MGEX station products. Which is characterized by comprising a plurality of satellite systems, such as the WHU (Wuhan University) products include GPS, GLONASS, Galileo and Compass.
Finally, all of IGS / MGEX data and products can be downloaded from the IGS data centers, you can refer to the table given IGS Data Center. Which lists all FTP address global and regional centers of.
