Insofar the ambition of navlist is to '..preserve..' , consider this might at least a minor success. I have started CelNav only 2 years ago, and took my first airborne sightings last week.
Thanks to all the clarifying posts by Greg and Gary and others, these greatly helped me. A brief report:
Flying from Canary Islands (27d47 N, 15d30 W) in a RANS Coyote microlight (i.e. a Light Sports Aircraft, very wobbly indeed) using my Mk. IX sextant. On SSE course, repeated runs towards the sun at between 1000 and 1100 UTC. Sun and moon both in the 20-25 degree altitude range, but the moon too weak for a good sight. Thus only Sun LOPs taken.
Best shot: distance from actual (GPS-) position to LOP was 1.9 nm. That was satisfying.
I did not do pre-computation because I am still in the process of figuring that out. Also, the Polhemus is of limited use because this aircraft's speed at 80 mph falls below the minimum value of the Polhemus at 90 kts.
Any comments, suggestions, questions welcome.
Eric
