Mounting location

This section provides information on determining the best location
for the HS60.
GPS reception
When considering where to mount the HS60, consider the following
GPS reception recommendations:
•
Ensure there is a clear view of the sky available to the HS60 so the
GPS and SBAS satellites are not masked by obstructions that may
reduce system performance.
•
Since the HS60 computes a position based on the internal GPS
antenna element, mount the HS60 where you desire a position with
respect to the GPS antenna (located on the side of the recessed ar-
row on the underside of the enclosure).
•
Locate any transmitting and other GPS antennas away from the
HS60 by at least several meters to ensure tracking performance is
not compromised, giving you the best performance possible.
•
Make sure there is enough cable length to tie into the NMEA 2000
backbone of the vessel.
•
Do not locate the antenna where environmental conditions exceed
those specified in Environmental specifications, chapter 5.
HS60 environmental considerations
The HS60 is designed to withstand harsh environmental conditions;
however, adhere to the following limits when storing and using the
HS60:
•
Operating temperature: -30°C to +70°C (-22°F to +158°F).
•
Storage temperature: -40°C to +85°C (-40°F to +185°F).
•
Humidity: 100% non-condensing.
VHF interference
VHF interference from devices such as cellular phones and radio
transmitters may interfere with GPS operation. For example, if install-
ing the HS60 near marine radios consider the following:
•
VHF marine radio working frequencies (Channels 1 to 28 and 84 to
88) range from 156.05 to 157.40 MHz. The L1 GPS working center
frequency is 1575.42 MHz. The bandwidth is +/- 2 MHz to +/- 10 MHz,
