C++ code for creating a Skyplot of GPS satellites.
The technical paper which describes the Skyplot software is published in
GPS Solutions, Volume 6, Number 1-2, 2002, pp. 118-120.
The readme.txt file explains how to run the skyplot.exe program which was
compiled on Windows NT using Borland C++ Builder 5.0 . The program is not
menu driven but instead reads an input file which supplies the program
with a time window, a GPS ephemeris (either an SP3 or a RINEX NAV file),
the coordinates of the point viewing the satellites (in XYZ or lat/long/ellhgt),
and an elevation mask below which no satellite tracks will be plotted.
