The antennas in this case are fixed, though a movable solution would be
nice. the problem is how to get the tracking program to point the antennas
at a fixed spot and keep them pointed there. I'm considering the assembly
of a sat-gate that will do double duty on sats and terrestrial work so the
antennas need to be able to "track" both types of targets. notice the
quotes around "track"...ultimately I'd like to just specify an oblect (norad
catalogue number or lat/lon) remotely and have the antennas point and remain
pointed at the object as my station and/or the remote station (object)
moves. Im thinking to just have the tracking program pull the right set of
keps....but I need to create them first! I'm also open to ways to do this
in ways that may be easier. suggestions are welcome.
