Retrieved from http://geodesy.blog.sohu.com/274775667.html IGS has three global data centers: CDDIS, SOPAC, and IGN, providing free pseudorange and phase observations, broadcast ephemeris, weather and other measured data (Data), the main download addresses are CDDIS (ftp://cddis.gsfc.nasa.gov), SOPAC (ftp://garner.ucsd.edu/), IGN (ftp://igs.ensg.ign.fr /)Wait.
IGS has 8 analysis centers, providing products such as Ultra-rapidly, Rapid and Final satellite orbits, clock differentials, etc., to meet the application research needs of scientists and engineers around the world. The analysis centers are 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/), etc.
The ZPD products of IGS stations started in 1997. Each station has one file per day. The file naming format is ssssddd0.yyzpd, where ssss is the ID of the IGS station, ddd is the accumulated day of the year, and yy is the year. The file download address is ftp://cddis.gsfc.nasa.gov/pub/gps/products/troposphere/zpd/, and the file directory structure is set for the installation year and annual accumulation date, such as the absolute path of the ZPD product of usno on the 200th day in 2013 It is ftp://cddis.gsfc.nasa.gov/pub/gps/products/troposphere/zpd/2013/200/usno2000.13zpd.gz.
The time resolution of ZPD products is 5 minutes, and ZPD is in millimeters (TROTOT- Total zenith path delay [mm]).

Let me talk about GNSS observation data (data). At present, IGS/MGEX, US CORS, and Hong Kong CORS are mainly available for downloading observation data. Of course, IGS is the most used, which is characterized by a large number of sites (more than 400) and global distribution; MGEX is a sub-project of IGS used to track multiple GNSS systems. The number of sites has reached more than 100, which is characterized by global distribution. It also includes observations of various satellite systems such as GPS, GLONASS, Galileo, Beidou, QZSS, RNSS, etc. you may have heard of. For several other CORS systems, the US CORS data is free for download, and the Hong Kong CORS data can also be downloaded for free, but registration is required.
As for the data of various provinces and cities in China, such as CORS, land state network, iGMAS, etc., z is at least classified at present and needs to be approved at various levels, and most people don't even think about it.
Besides products such as precision ephemeris and precision clock errors, all major IGS analysis centers (MIT, SIO, GFZ, etc.) will produce their own precision products. Its product file is prefixed with the center abbreviation (for example, sio18120.sp3), and finally the final product (IGS, IGR, IGU) prefix is obtained by the weighted average of the products of all IGS analysis centers. IGS currently only provides products that include GPS and GLONASS satellites.
As a sub-project of IGS, MGEX currently has products based on MGEX stations. It is characterized by multiple satellite systems. For example, WHU (Wuhan University) products include GPS, GLONASS, Galileo and Beidou.
Finally, all IGS/MGEX data and products can be downloaded in each data center of IGS, you can refer to the table given by IGS Data Center. The FTP addresses of all global centers and regional centers are listed above. For domestic use, Wuhan University FTP is the fastest.
