  • Patent number: 5798733
    Abstract: A position guidance apparatus is a microprocessor based tool used to aid a parachute jumper in reaching a predetermined target position in an interactive manner. The device is particularly valuable in aiding those who have to do parachute jumps under hazardous conditions such as at night, into terrain with no visible orientation features, or into terrain wherein a precisely located landing is desired. The position guidance apparatus provides locational/directional guidance in a visual and potentially audible manner to guide the user in steering himself into an appropriate targeted landing zone. The apparatus is one that is preferably strapped onto the forearm of a user and provides a small graphical display of current position, target position, and predicted destination position. Alternatively, the display can be implemented as a heads-up display for the user.
