For SATgate PHG circles:

The PHG circles in APRS can be extended to show
circles of over 1000 mile radius I think, though 
few client software's implemented it.  We extended
PHG to that range just so that Satellite PHG's could
be displayed.  These could also be displayed for
SATgates, but projected upward they are dependent
on the satellite's altitude.   

TO get that large of a PHG, just extend the alphabet
above the "9" digit in the "H" byte of the PHG. For 
example, for Balloons, use "=" which is about 82,000 feet
or "A" which is about 1,300,000 feet or about the
height of the Space Station...

But again, few other software than APRSdos
probably implemented it...

Very fine but I would suggest you to show something that findu not give us:
a map with only satellite igates without the igated stations. If each
station had a circle showing the action radius it should be very useful.
Many igates are not shown on maps of APRS.
