The Kepler Manager

What is the Kepler Manager?

The Kepler Manager allows you to interface with the Space-Track Web site to download two-line element data.  Additionally, with the registered version, you can also use the automation features of the Kepler Manager to keep your Kepler data up-to-date for both the multi-line Kepler data required by real-time tracking programs such as WXtrack and the historic Kepler data required by programs like SatSignal and the HRPT Reader for processing non real-time data.

The Kepler Manager requires that you are a registered use of Space-Track Web site.  Please visit that site to register - it's free!



Can I register the Kepler Manager and what do I get?

Your registration would be appreciated to help support continued developments.  If you register the Kepler Manager (by registering my WXtrack software) a number of extra features in the Kepler Manager become available:

  • a new menu option in WXtrack (Tools, Kepler Manager) allows you to run the Kepler Manager from within WXtrack (requires WXtrack V3.4.8 or later).
  • you can run the program with command-line a parameter -AUTO or -START to provide fully automated, hands-off updates of your Kepler data.  Use the Windows scheduler to provide regular updates (e.g. twice a week).
  • you can provide a list of your own favourite satellites to be retrieved in addition to the standard bulk catalogues. You won't have to request changes to the Space-Track site and wait for items to be added.
  • the program can automatically update any multi-set historical data files that you have such as those used by my HRPT Reader program and other software.

A Kepler Manager licence is included in the WXtrack licence.  The Kepler Manager will provide data for any programs using the standard two-line element Kepler data - WXtrack does not need to be running - just licenced on the PC where the Kepler Manager is running to get these additional functions. 


Getting the most recent data

One oddity I've noticed is that the individual satellite data - where you enter the catalogue numbers into the list - sometimes have more recent Kepler data than the combined lists.  So, for example, if you want the most recent data for NOAA-18, enter its catalogue number (28654) into the list rather than just relying on it being present in the weather group.



  • You must be a registered user of the Space-Track Web site
  • You must be running Windows XP SP2, Vista, or Windows-7/8 on a 500 MHz PC with 256 MB of memory or greater.  Older Windows versions are unlikely to  work and are not supported.
