CamSextant 4+

CamSextant allows taking altitudes of celestial objects using your phone as a sextant. It is a complete celestial navigation solution, with instrument, almanac and celestial calculator. Point a celestial object and tap the image to capture the altitude and time.

Stars and planets shown on screen in real time. Show constellation names and lines. Identify planets and navigation stars (from Hipparchus 150 catalog). The program can also speak the star names and altitudes (audio).

Astronomic Position (AP) is automatically calculated once you have two sights.
Calculate your astronomical position with less than 10 clicks.
Perpetual nautical almanac using Astronomical Algorithms ( book by J. Meeus).

If you take altitude observations of the same object, the average time/altitude are shown.

You can calibrate the sextant horizon by reading the sea horizon altitude.
Note that the phone is more like a bubble sextant: you don't need the sea horizon to use CamSextant.
Anyway, click [Calibrate] button to save the correction.
Calibration angle is subtracted from raw sensor reading.

If you have a marine sextant at hand, you can edit the altitudes captured by the phone and get serious celestial navigation work done.
