Global Positioning System / Global
Navigation Satellite System
The Global Navigation Satellite System (GNSS) in the
radio uses information from the Global Positioning
System (GPS) to determine the approximate
geographical location of your radio. The geographical
location is expressed as latitude and longitude or
Military Grid Reference System (MGRS) format per
request from customers.
Note:
This feature is addressed as GPS across the
manual as the naming convention of the
buttons and strings remain the same as the
legacy feature of GPS.
The availability and accuracy of this location
information (and the amount of time that it takes to
calculate it) varies depending on the environment in
which you are using the GPS feature.
For example, GPS location fixes are difficult to obtain
indoors, in covered locations, between high buildings,
or in situations where you have not established a
clear broad view of the sky.
Once GPS is enabled, the radio displays the GPS
icon on the screen. The dispatcher can always
request the system to determine the real-time location
coordinates of the radio.
GPS Operation
The GPS technology uses radio signals from earth
orbiting satellites, to establish the location
coordinates, maximizing your view of clear
unobstructed sky is essential for optimum
performance.
Where adequate signals from multiple satellites are
not available (usually because you cannot establish a
view of a wide area of the sky), the GPS feature of
your radio will not work. Such situations include but
are not limited to:
• Underground locations
