(32S II) Position, Distance & Bearing Calculations

[Gil]

I just checked, with the given reference,
some of the control results in that paper.

Note that the results are not at all accurate
when reviewed with Vincenty's formulae (error <= 1 mm). :

Point A in deg.mmssss
{ 66.53507 162.35557 }

Point B in deg.mmssss
{ 66.50033 161.02032 }

Correct results:

Bearing forward 1 D.mmss¦ 264.513132284
Backward :2 D.mmss¦ 90: 83.2511696433
effective distance on geoid/Earth surface
[km]: 68.981609066,
or 42.8631846678_mi'
≠indicated 42.7 miles

Besides, Euclidean distance through the Earth (initial altitude 0¦end altitude 0): 68.9812747629 km.

See also, further down, the Post
"Geodesic distance & Earth Euclidean distance calculator, bearing calc", Ver06b.hp for HP50G calculator.
