Hi Greg,
Er, no. While manually plotting this would indeed be futile, I was thinking more of Star Pilot, or the like, as a test of the pixel method.
Clearly, your position is know as is the time of the picture. I believe your fix will shift left or right dramatically as the precise pixel height shifts by one pixel. Of course its sensitive, as a function of the extraordinarily shallow crossing of the LOPs.
You've got nothing to lose. Why not try it, and in addition, shift by one pixel either way. At worst, we blame the shallow LOPs. At best, you have a good fix.
Its a once in a lifetime deal, and as you have worked extensively at the CCD method, it may just be the icing on your cake!
Best Regards
Brad
Brad,
The difference in azimuth is only 0.2* so the two LOPs will be basically parallel. No fix. Just an estimated position. If the Moon were involved (eclipse) then one image would generate two parallel LOPs and a lunar longitude for a true one shot fix. You are thinking of the LOP/ex-meridian single observation fix which has about a 10* azimuth difference (not really a fix but a form of running fix).
