Hi,
A problem that I've had for many years is how to track when the satellite's azimuth crosses across the rotator's end-stop, ie. when the azimuth changes from 0 to 359 degrees.
My rotator turns between 0 and 450 degrees, so it should be possible to use angles between 360 and 450 to overcome a sudden transition from 0 to 360 degrees.
As the pass data is available within the tracking program, it should be feasible to deal with the problem in the program. Do any tracking programs include this feature?
A possible solution would be to use a small PIC between the computer and tracker, which could modify the commanded azimuth.
I'm using a Yaseu 5500, LVB tracker, Sat_Explorer tracking program and WinXP.
Any help, suggestions or comments would be most welcome.
