standard GNSS antenna closer to the wheelhouse,
but out of the radar or satcom beam path and the
L-band antenna high on the mast. For best
performance, do not allow more than 7dB of cable
loss between the antenna, NavCom Combiner (2:1
with 6dB LNA, SF Notch & Passbands) and the
receiver. Applications without the Tall L-band antenna
and operating at high latitudes should mount the
GNSS antenna high on the mast, with the same
considerations for beam path avoidance and cable
loss limitations.
NavCom provides a tool on our website to aid in
determining when the High Latitude L-Band Antenna
Kit is appropriate to use. This tool is for the
SF-2050R, but also applies to the SF-3050
High Latitude L-Band Antenna Kit due to similarities
in the primary antenna performance.
GNSS Sensor
Mount the SF-3050 GNSS sensor to a flat surface.
Shock isolators suitable for 0.50kg (1.1 lbs) may be
necessary for environments with high vibration, i.e.
Earth moving equipment or aircraft installation.
Do not place the sensor in a confined space or where
it may be exposed to excessive heat, moisture, or
humidity.
MED Compass Safe Distance: The
SF-3050 receiver may not be installed
closer than 250mm to the ship’s compass.
The SF-3050 can be installed in a backpack for
mobile surveying applications.
