How can I access hourly GNSS data files?

Hourly GNSS data files are available through anonymous ftp and other methods. Hourly GNSS data are available for the last three days. These data are removed after that time since files containing a full day's worth of data are available.

Access the hourly GNSS data by using one of the following methods:

• anonymous ftp at URL ftp://cddis.gsfc.nasa.gov/gnss/data/hourly/. NOTE this method will be discontinued in October 2020
• via https at URL https://cddis.nasa.gov/archive/gnss/data/hourly/
• via ftp-ssl using the command line and gdc.cddis.eosdis.nasa.gov

Detalied information and examples for using these methods can be found on our Achive Access page.
