Systems and methods are provided for two-stage location. In one
implementation, there is provided a method for receiving a first location
of a first radio, the first radio providing the first location of the
first radio; using the received first location to determine when to
transmit an activation command from a portable locator to a second radio,
the second radio coupled to the first radio; and receiving at the
portable locator a beacon transmitted to enable the portable locator to
precisely locate the second radio and the coupled first radio.
