3.3 Distance measurement
Because the units were designed, and calibrated for certain distance operations the
higher distance will decrease the availability. GeoDesy FSO pre-calibrates and pre-
tests every unit shipped to the customer. To ensure that the unit you are about to
buy fits to the needs, the first step
is to measure the distance. The
best way to measure it is by GPS
(Global
Positioning
System), these units
are accurate enough to
determine the distance
between two points.
For
more details
please refer to the
GPS
manufacturer
handbook. Also there are several
other ways to measure the
distance. If you know the exact
address you can use mapping software like MapPoint or Auto route.
3.4 Direct sunshine
To prevent the sun
shining directly into the
receiver optics, first one
has to determine the
orientation of the link.
Try to avoid East-West
orientation wherever it
is possible. Examine
both sides of the link at
sunset and sunrise and
find a position where
the sun cannot get
behind any of the heads. Be aware that the path of the sun is changing throughout
the year.
