Yesterday was a good day in Auckland, so got some measurements. But before, got the correct numbers with Google Maps and with F-Droid SatStat:
12:15PM
Google Maps
===========
Lat -36.8479814
Lon 174.7666313
SatStat
======
Lat -36.84810 (and also 1 minute later after recalibrating -36.84709)
Lon 174.76725 (ditto above 174.76687)
Altitude: around 102 m (GPS can be very imprecise for that)
Azimuth 273 W
Bearing 169 S
Then with the sextant and artificial horizon:
12:25 PM
67.4
33.7 (/2)
And Wikipedia:
Lat: 36.8482°S
Lon: 174.7668°E
That divided by two, would be 33.7. Combined with the correct longitude, plotted on Google Maps:
Now need to learn about Dip to compensate for the height.
