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-36).
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
