GNSS battery packs.
Integrated Antenna

Refer to Appendix B for detailed
specifications on the integrated antenna.

Antenna placement is critical to good system
performance. Avoid antenna shading by buildings,
rooftop structures, foliage, hills/mountains, etc.

Choose a mounting location with obstructions
as low as possible (preferably below the horizon),
where the antenna 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 receiver 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.

Avoid placing the antenna on or near metal or
other electrically reflective surfaces.

Do not paint the antenna enclosure with a
metallic-based paint.

Avoid placing the antenna near electrical motors
(elevator, air conditioner, compressor, etc.)

Do not place the antenna too close to other active
