Solar Observation
6XUYH\ 6RODU 2EVHUYDWLRQ
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.
6HWWLQJV : located at the top of the screen, is a shortcut
to the Date/Time Settings screen (Page R-39).
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 ,
