ABSTRACT:
An air-deliverable global positioning system (GPS) position marking device nd method involves the operations of providing an air-deliverable GPS position marking device, launching the device into flight through the air to a desired location, arming the device in response to launching the device into flight, firing a detonation mechanism contained in the device when the device is at the desired location after receipt of a magneto-inductive transmission so as to generate a predetermined pressure in an interior chamber of the device that causes ejection of a payload assembly from the interior chamber, initiates inflation of an inflatable flotation body of the payload assembly, and initiates communications between a GPS receiver and transmitter unit in the payload assembly and a remote station to determine the position of the position marking device at the desired location.
