28.2°E is on a meridian somewhere towards the far end of the Med. I'm
guessing an Arabic station? Obviously the satellites are all near the
Equator in terms of lattitude.


28.2°E is the position of the Astra 2A, 2B & 2D satellites used by
Astra and the satellites have to be directly over the equator.

If they were not, they would wander north and south of the equator over
a 24 hour period and need a sophisticated steerable dish to track them.

The dish needs to point to a spot in the sky which is 28.2°E of the
Greenwich meridian and 35,786 kilometers (22,236 miles) above the
equator - finding this point is the clever bit!
