Solar Observation
Survey Solar Observation.
The Solar Observation screen is used to compute the azimuth to an
arbitrary backsight based on the position of a celestial body; typically
the sun.
WARNING! Direct viewing of the sun
without a proper filter will cause serious eye
damage. Pointing a total station directly toward the
sun without a solar filter can also damage the EDM
components.
Find Azimuth Using Ephemeris Data: select this
method if you plan to enter data from an ephemeris.
Find Azimuth Using Date and Time: select this method
if you do not plan to use an ephemeris.
Note: The fields within the Solar Observations screen
will vary depending on the method selected above. All of
the fields from each method are described below.
Lat. / Long.: is the latitude and longitude of the total
station. These values can be scaled from a map, such as a
U.S.G.S. 7.5-minute quadrangle sheet or collected with a
handheld GPS unit.
Aim: selects the portion of the celestial body that where
you intend to aim. You can select Left Edge of Center,
Center, or Right Edge of Center.
