NAME 

SpaceTrackTk - Perl/Tk application to fetch satellite orbit data.

SYNOPSIS 

This application provides a windowed interface to the Astro::SpaceTrack module, based on the Perl/Tk windowing system. All you do is issue the command 
 $ SpaceTrackTk

You will be presented with a splash screen, followed by a login window. In order to get full functionality, you must have a Space Track account. It is the username and password of this account that you enter into the login screen.

You have the option to skip the login. This gives you reduced functionality, since you are limited to the data provided by redistributers known to Astro::SpaceTrack. The reduced functionality is apparent in two ways:

* The Space Track sources do not appear in the ``Object ID source'' drop list.

* The ``Include common names'' checkbox does not appear on the retrieval window, since you get whatever the redistributer provides.

ENVIRONMENT 

If SPACETRACK_OPT sets direct to 1, the login screen is skipped, and the functionality is as though you skipped the login (i.e. reduced). Otherwise, if a username and password are available from either SPACETRACK_USER or SPACETRACK_OPT, you are logged in automatically and the login screen is skipped.

Please see Astro::SpaceTrack for the details.
