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.
NOTICE:
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 location coordinates. Therefore,
maximizing your view of 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
• Inside buildings, trains, or covered vehicles
• Under any metal, or concrete roof, or structure
• Between tall buildings or under dense tree-cover
• In temperature extremes outside the operating limits of
your radio
Even where location information can be calculated in such
situations, it may take longer to do so, and your location
estimate may not be as accurate. Therefore, in any
