Hi Fred: I have some parts of the MD-1 Automatic Astro Compass system, but so far have not been able to get the detailed information needed to make the star tracker operational. I have some information at: http://www.pacificsites.com/~brooke/MD1.shtml As far as I know the MD-1 was only used on the C, D, E and F versions of the B-52. Also related to the subject is the shoot down of KAL flight 007. This appears to have been caused by the combination of improper use of the inertial navigation system and the similarity of the resulting course to ones flown by U.S. electronic intelligence aircraft. This was the trigger event that caused the U.S. to open the GPS system to public use.
