  • $\begingroup$ What do you mean by "entrance altitude to Earth's atmosphere"? Are you asking at what height Earth's atmosphere ends? $\endgroup$ – zephyr Aug 11 '16 at 12:37

  • $\begingroup$ I was going to suggest the JPL Fireballs page which records detected explosions. Typically 30-40 km altitude (highly variable) and as much as a few kilotonnes of impact energy. (The Chelyabinsk meteor is on the list too.) $\endgroup$ – Andy Aug 11 '16 at 13:33

There is a example here of the process required. But basically you need observations of the track from two locations and then just perform some relatively simple trigonometric triangulation. The Nemetode network regularly does this using images from a network of cctv cameras.
