The Global Positioning System (GPS)
This feature uses information from the Global Positioning 
System (GPS) satellites orbiting the Earth to determine the 
approximate geographical location of your radio, expressed as 
latitude and longitude or MGRS format per request from 
customer. 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 very 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.
Understanding the GPS Feature
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
