I’m currently in the process of digging out a dual axis motor from storage. It’s been there a while so it’s going to take a bit of time. Hopefully I’ll get it all set up soon so I maybe in a position to chase an inclined orbit satellite or two. That’s how I managed to come across some old publications and that particular article.
As is normal, inclined satellites do not have transponders with TV/radio programs, but only Data. The cost of a slot is obviously lower, and operators have followed and tracked them via auto tracking.
If you want to find such satellites, try 24.5W Intelsat 905 inclined 2.3° or NSS-7 about 5.2°, where there are many date transponders. For NSS 7, look for the satellite between certain hours of the day, because the tilt is so high that you don't see any signal at all, as if the satellite disappeared from the arc.
If you don't have elevation control, position the antenna between certain hours, usually in the evening, and then you will notice how the signal decreases or increases. Because it can lock some of these transponders with s2x extension cards with a sensitive tuner, so it can display the signal in real time, and a Crazyscan application.
Here's a time when the signal at 24.5W is as much as I was looking for.
