the connector into place, and then turn the connector’s locking ring to

14.1 GPS And Unobstructed Line Of Sight
GPS receivers operate by line of sight with global positioning
satellites. A receiver must be able to get signals from at least three
satellites in order to calculate longitude and latitude (there are
currently 30 GPS satellites orbiting the earth). The more satellites a
GPS receiver can “see,” the more accurate and reliable the
positioning.
For a GPS-equipped RAELink3 (or any other GPS device) to work
properly, it must have a direct line of sight to a satellite, meaning it
will not work well (if at all) indoors. Although radio signals from
navigation satellites can pass through clouds, glass, plastic and other
lightweight materials, satellite navigation receivers do not work
underground or in other enclosed spaces.
If you need to operate a monitor under a roof or anything else that
obstructs a clear view of the sky, you may need to take the RAELink3
outdoors into a nearby clear area, perform a manual GPS Coordinates
Check (see page 25), and then either allow those coordinates to be
used on maps in ProRAE Remote running on a host computer, or
input them manually.
