	    XSAT 1.4 - a satellite tracker for the X Window System

XSAT is an X-based satellite tracker which draws maps of various world regions
and plots satellite ground tracks, complete with timestamps.  XSAT also pro-
duces a list of visible orbit passes for a given city, with extensive infor-
mation on azimuth, and time.  It can also produce a PostScript file which
gives a hard copy of all displayed information.

XSAT uses Athena widgets exclusively, along with a Canvas widget of its own,
and therefore should easily port to a wide variety of systems.  A patch file
is included which modifies XSAT version 1.2 for Solaris 2.3 systems.

A recent (2/28/96) set of satellite data is provided, along with a C shell
script which retrieves updated element sets from NORAD via anonymous FTP.

XSAT was written by David A. Curry, N9MSW (davy@ecn.purdue.edu); enhancements
were made by Terry R. Friedrichsen, N7XJO (terry@venus.sunquest.com).  Solaris
2.3 patches by Mike Porter (mike@strauss.udel.edu).
