Figure 15: Standard GPS/L-band Antenna
Antenna Location
When choosing an antenna location, consider the
following:
Locate the antenna as high on the mast as
possible, where it has a clear view of the sky, to
an elevation angle of 7º if possible. Obstructions
below 15º elevation generally are not a problem,
though this is dependent on satellite availability
for the local region.
Avoid placing the antenna where more than 90º
azimuth of the sky is obstructed. When more
than 90º of azimuth is shaded, it is often still
possible for the reciever to navigate, however,
poor satellite geometry (due to satellite shading)
will provide poor positioning results. Even 10º of
shading can have a negative effect on
performance, though this generally is not the
case.
