Are you saying you have the altitude and azimuth of the satellite indicated by your very expensive tracking telescope plus the position of the satellite obtained from either the photograph or the mathematics of the satellite's motion? In theory it is possible. Arthur Whitten Brown was suggesting as much in a letter to Flight Magazine somewhere between being released from POW Camp in 1918 and the Atlantic flight in 1919*. The problems of course were accuracy of the azimuth reading, the one in 60 rule, and the fact that the bearing from the astral body to the observer is not the bearing of the body from the observer -180°.

* I'm fairly sure I found this by chance in the Flight Magazine Online Archives whilst researching Brown's navigation on the 1919 atlantic flight.
