Following my answer to G22879, on March 15, I come back to Round 2 of Jeremy C.
Using ASTROLAB v3 and French Nautical Ephemerids, the result is as follows :
L = 20° 38.79'N G = 120° 48.6'E
DOP = 1.08 sigma = 0.44 NM
This fix is about at 0.3 NM from the GPS position.
As compared to Peter Hakel data, I noticed a slight difference between Capella's GHAs, which can partly explain my shift from GPS position.
That is a good example.
Thank you Jeremy.
Thank you Peter and Antoine, too.
