NavList:

I make the position and time of the LD to be:

+ 46 deg 36' 26.955985" OR 46 deg 36.449266' OR 46.607488deg
+ 2 deg 29' 1.483475" OR 2 deg 29.024725' OR 2.483745deg
+ 0 hr 23 min 35.285337 sec
F= 2.904631510617057E-004

I set up an 'error' equation to find the RMS difference between the 4 computed and calculated angles (3 altitudes and the LD) as a function of final Lat, Long, and time difference (F above). Altitudes and LD calculated using USNO NOVAs and JPL DE405 as inthe previous problem. I use the time offsets from the input data set and the Lat and Long offsets calculated as shown by others. The search algorithm then iterates to minimize the 'error' function. Voila!

Summary of results attached.

Thanks for the exercise!
