In the early days I believe they relied on Flight International magazine, and other sources, for the inclination, etc.

I. have been reading up on the history of the Kettering group and I am particularly curious about one thing: how did they determine the orbit of the satellite strictly from observation. Can anyone help me with this?
I can see how you could pick up the period of the satellite from observation, but am stumped as to how the rest of it is worked out...
