    receiving communication signals from a local positioning system;

    receiving a position query at a communication device;

    determining whether the position query is from an authorized party;

    discarding the position query in response to determining that the position query is from an unauthorized party; and

    transmitting data related to the position from the communication device to the remote communication device in response to determining that the position query is from an authorized party; and

    in response to determining that the position query is received from the position query button;

    determining whether the communication device is in communication with the remote communication device;

    transmitting the data related to the position from the communication device to the remote communication device in response to determining that the communication device is in communication with the remote communication device; and
