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: Consolidated Laser Ranging Prediction Format (CPF) of jason-2 mission
After asking our Jason-2 provider, they told us that they do not provide H5, 20, or 30 records for Jason-2. The reasoning for this is that H5 records are only used for "cannon ball" satellites (LAGEOS, ETALON, Stella, etc.) where the center of mass is stable (not affected by fuel distribut...

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: 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 ...

Re: Precise Orbit Determination products?
IGS analysis centers provide satellite orbit solutions to the CDDIS using pre-determined schedules, e.g., sub-daily, daily, or weekly, depending upon the data product. The IGS analysis center coordinator retrieves these solutions and produces a combined product, which is then in turn archived at the...
