Device Introduction & Feature
This device, which is a Digital Sextant having the same shape as the
conventionalsextant, can automatically calculate the position of the
observer by measuring the altitude of a celestial object(the sun, the moon,
planets and some navigationalstars) at sea.

⚠Horizon Shade Glasses
It is used to protect the eye of the observer by adjusting the intensity of
light when measuring the altitude angle of the celestial body.
⚠Horizon Glass
The left half is m ade of transparent glass, so the horizontal line is visible
directly. And the right half reflects the shape of the measured object
reflected though the Index Mirror.
⚠Index Shade Glasses
It is used to protect the eye of the observer by adjusting the intensity of
light when measuring the altitude angle of the celestial body.
⚠Index Mirror
The shape of the measured object is reflected.
⚠Digital Unit

How to Use

There are SIMPLE SIGHT MODE and NORMAL SIGHT MODE
in the measurement methods of this equipment.
SIMPLE SIGHT MODE is used when urgently measuring the
bottom of the sun to calculate the position. The following
environment variables are set as the default values and cannot
be changed;
Temperature : 10°
Atmospheric pressure : 1010mbar
Measurement altitude : 10m
⚠However, the error of calculated position may be very large
when SIMPLE SIGHT MODE is used.
NORMAL SIGHT MODE is generally used for sighting.
environmentalinformation(temperature, atmospheric pressure,
measurement altitude)should be input when observing.
In addition to the sun, about 67 objects can be observed.

4. If it is set as 000°00.0, you can
make celes tial obs ervations
imme diately. Howeve r, if it is not
set as 000°00.0 like the picture on
the right, you have to set 0(zero) by
pressing the button of .
6. Move the horizon in the center of
the le ft side of the Horizon Glas s
while looking at Telescope.
7. Move Index Arm with Lever and
place the celestial body to be
observed on the right side of Horizon
Glass.
How to Use
Horizon Glass

⚠Caution
For accurate zero-point control and position calculation, the Micrometer Drum
must be operated clockwise. If Micrometer Dum has moved beyond the
desired range by user, it should not be moved in the counterclockwise direction.
It may cause errors due to the characteristics of the device. In this case, the
sighting should be done from the beginning again to adjust clockwise.
8. Adjust Micrometer Drum so that
the bottom of the celestial body to
be observed can touch the horizon.
9. Swing the device right and left to
determine the position of the
observed celestial body.

1. ONE-BODY FIX
One-time measured value + Azimuth value of the celestial body
Ifyou know the celestialazimuth, make a single measurement to calculate the
position.
2. TWO-BODY FIX
Two-time measured values
The position is measured twice with the vesselstationary or moving to obtain
two pos ition value s .
The observerdetermines which of values to choose.
3. Three-time measured values
Measure the position three times with the vesselstationaryor moving.
Average the three observed results(1st-2nd, 1st-3rd and 2nd-3rd), locate the
center point and check the location.
