I was thinking in something already prepared for interactive orbit 3D visualization.

Hello again. I've found that STK is not free, but a 1 week trial. Anyway is difficult to use. I'll continue searching other free programs

Hello What I really want is to visualize and measure the angle that form the satellite, the Sun and some point on the Earth surface. Maybe like if you had a CAD o math program able to create spheres in space and draw planes, intersections and measure angles. The advantages of Orbiter would be...

Hello I'd like to visualize by myself how is the angle at which we see a satellite at dawn, seen from different latitudes. I mean, I need to place an Earth, a satellite, and the sun, and visualize the angle they form in 3D. I'd need to trace Sun's rays (to check dawn condition) and project the...
