A method and system provides for controlling operation of registered
devices using the Global Positioning System (GPS). One or more devices in
a mobile environment are registered with a GPS navigation system of the
mobile environment. In response to the mobile environment moving from a
first location to a second location, the GPS navigation system retrieves
local law information that specifies or defines the second location using
GPS coordinates of the second location. Whether each device of the one or
more devices registered with the GPS navigation system is in violation of
the local law must be determined. If so, the GPS navigation system
automatically controlling operation of each device in violation of the
local law so as to not be in violation of the local law.
