Abstract
A position locating device comprises a position determining unit for periodically determining the position of the device and storing position data in a memory. On activation of the device, a position transmitting unit periodically transmits a terminal identifier and position data, to a base station via a satellite. A power management unit controls the periodicity of the transmission by the position transmitting means. A position determining system includes the position determining device and a base station for receiving the terminal identifier and position data and relaying the information to a first responder.
Claims16
A position determining system comprising:
- a position locating device including a position determining unit which periodically determines the position of the device and stores position data in a memory, a position transmitting unit which, upon activation, periodically transmits a terminal identifier and position data to a satellite, and a power management unit which controls periodicity of the transmission by the position transmitting unit;
- and
- a base station that operates to conserve battery power remotely from said position locating device by adjustment of said periodicity, and that includes contact means for contacting a first responder and, when no response is received from the first responder, contacting at least one other responder.
