Re: wget download sp3 files

The most common problem is that the .netrc file is not set up correctly. That file also has to be in your home directory. Here is a link to the instructions for setting it up: https://cddis.nasa.gov/Data_and_Derived ... cFile.html

Question: Data Merge for different time periods

Re: Data Merge for different time periods

The CDDIS does not generate the data; it is just archived in our system as daily files only. We do not have any tools that would merge files into a specific time range. Perhaps someone at the International GNSS Service (https://www.igs.org/) can help.

Re: MGEX navigation files (brdmDDD0.YYp.Z)

After 21-Jun-2020, the provider of these files stopped uploading them regularly to the CDDIS because the short name MGEX files are being phased out. The files are still available in long name format (BRDM00DLR_S_YYYYDDD0000_01D_MN.rnx.gz) under https://cddis.nasa.gov/archive/gnss/data/campaign/mgex/...

Re: GNSS navigation ephemeris

Registering with Earthdata Login is only required for HTTPS access. If you want to use ftp-ssl with a tool like FileZilla you will need to enter in the following: Host: gdc.cddis.eosdis.nasa.gov Port: 21 (or leave blank for the default) User: Anonymous Password: <<Your EMAIL ADDRESS>>

Re: Perl script to download hourly GNSS data

To change from using ftp to ftp-ssl in a Perl script, you will need to change more than just the URL. You will need to use a different library such as Net::FTPSSL. You can also make the calls via HTTPS using something such as Net::HTTPS or use another library like Net::Curl. No matter which way you ...
