Data Download and File reading

[mariamalmarwani]

Hello,
I am trying to download GPS ephemeris Data (or orbit determination data) for a specific satellite Block. However I am unsure which file to use to find the data I need within a specific time frame, and what software to use to then read the downloaded files.
Any help would be appreciated, thanks!

Hello,

I am not sure whether you want daily or hourly data, but we have information on broadcast ephemeris data at:

https://cddis.nasa.gov/Data_and_Derived ... _data.html

That page includes information on how the files are named and where they can be found in the archive. This page:

https://cddis.nasa.gov/Data_and_Derived ... ccess.html

provides examples of how to download the data using various methods. Let us know if you need further assistance.
