I think the answers are here. No one has yet provided images of satellites moving in the direction of the poles during sky radar, perhaps because. that radar shows the true state of things. The real value of the sun, moon and satellite position above us.
As far as non-geostationary satellites like GPS, the brighter the satellite, the easier to see. Here’s a Japanese one called the “Disco Ball” (Official name ‘EGP’). It’s covered with mirrors so it’s relatively easy to spot.
Here’s an image of it from earth:
EGP is in a nearly circular orbit at an altitude of approximately 1488 km, close to the (not firmly defined) boundary between low earth orbit and medium earth orbit. The orbital period is 116 minutes, and the orbital inclination is 50 degrees.
Here’s its orbit:
If you want to see more, these are some of the brightest...Here’s a list of satellites to get your started on your adventures away from the ISS:
