I view satellites regularly and it is quite simple with night vision. I've seen the Star Link satellite groups a day after launch and have pictures of them, all in a row, more than a dozen and moving spectacularly fast. They published the launch so we knew it was them.

When viewing satellites it's easiest to spot them moving from west to east as they darken as they move east and that darkening event horizon acts quick and is north/south and moves west until midnight or so (depending on the time of year) when they no longer shine (presumably from the sun). If the earth was flat that event horizon would follow the the sun through the sky and make an arc from the southeast-south first and then move northwest/north from there but that is not what is actually viewed. 

Thermal does not see them, I think they are too far away or too cold.

When I asked Sungenis how could geocentric satellites work on a stationary Earth his answer (theory was his word) is surprisingly simple. Think of a roulette wheel. The ball can be spun around with the wheel not moving and it will stay in orbit. The ball can be spun around with the wheel spun the opposite way and the ball stays in orbit. The ball can be spun around and the wheel can be spun in the same direction and the same velocity and the ball will stay in orbit. In all these scenarios, if the ball is not spun it will fall so the one constant in all of that is the ball must move relative to the room, not the wheel. 

I hope this helps,
