I've never used Predict for tracking, but most rotor control programs allow you to specify a set of fixed coordinates to "park" the antenna. Maybe something like that would work for you? 73, Jim KQ6EA

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.

I guess that you have the rotor on a moveable
platform such as a truck,
spacecraft. watercraft, etc.
The look angle to the fixed object is the
reciprocal of the angle
generated by the tracking program.
It should work if the antennas are mounted 180
degrees from where they
would normally be mounted.

a local mountain top.
could a set of keps be derived such that this
just looks like yet another
satellite? How would this be done? Is there an
easier way?
