a) For vertical use (taking the altitude of a celestial body, distance measurement)
- The sextant must be perfectly centered on the screen (the default position of the sextant).
- The sextant scale(60°) must perfectly cover the whole screen (bottom to top).
- The 0°-scale must be perfectly match with the sea horizon; difficult when the u-boot is rolling in the sea (100% realism).
Position error when measurering celestial bodies: +- 120 sm ( = +- 1° error) or more
Position error and other use: acceptable
b) For horizontal use (running-fix, 2-position-fix, measure the angle between any two landmarks)
- The sextant must be perfectly centered on the screen (the default position of the sextant).
- Best to begin measurement from the center-point of the screen.
Position error: acceptable
