RE : your NavList post # 22612

What is interesting to me is how we can take the same data and get variations on results. This of course derives from the analysis of the LOP's to determine the fix...

This is a good case in point when you have scattered clouds and the spread of azimuths was poor on most of the lines, so you have many LOP's that are too close to parallel. Sadly, this is what the sky offered me at twilight, so it is what we need to make do.

For the solution: The GPS fix at 1900 LT that evening was:

Latitude: 8 deg 48.4N and Long 109 deg 45.0 E. My skymate Pro software, which is what I always use for consistency, gave me a fix of 8-48.3N and 109-45.05E.

Hello again Jeremy,

Quite late on that one ...

Own result is : N08°49'1 E109°45'2, i.e. 0.7 NM from your GPS Position at 19:00 LT. Such computed position is also within 0.1 NM of Peter Hakel's position. Hello Peter, I can even hear you this time !!!

So, jeremy, I am a bit surprised that "Skymate Pro" Software puts you within 0.1 NM of GPS Position, while Peter and I find a position which is 0.7 NM away from this same GPS Position.

Should I conclude that there a 0.6 NM position difference between our reults ?

Any comment on your side ?

Best Regards from

Kermit
