Question about .sp3 files

by CDDIS_support_Lori » Wed May 11, 2022 1:31 pm America/New_York

I am writing to ask how to find a .sp3 file with full records in CDDIS. I tried to get through all .sp3 files in "https://cddis.nasa.gov/archive/gnss/products/" and "https://cddis.nasa.gov/archive/gnss/products/mgex" and did not find a right one which was like that dipicted in the format document 'sp3c.txt' or 'sp3d.pdf'. Could you please do me a favour? Many thanks.

You have the correct directory locations for the different sp3 files. The short name sp3 files are located in https://cddis.nasa.gov/archive/gnss/products/, and the long name ones are in https://cddis.nasa.gov/archive/gnss/products/mgex. You just need to add the GPS week subdirectory you want after each location, so you are looking in .../gnss/products/WWWW/ and .../gnss/products/mgex/WWWW/.
