Patent Images
1. A portable terminal guidance system, comprising:
- a global positioning system (GPS) transceiver adapted to produce a GPS output signal representing the location of the terminal guidance system;
a terrain scanner adapted to produce an output signal relating to the characteristics of the terrain in the vicinity of the terminal guidance system;
a ceilometer adapted to produce an output signal relating to the visibility and the cloud cover in the vicinity of the terminal guidance system; and
a processor responsive to the radio, the scanner, and the ceilometer adapted to produce a data signal capable of being processed by a receiving aircraft into an obstacle avoidance approach path for the receiving aircraft.

Abstract
A portable autonomous terminal guidance system can be located in an aircraft landing zone. The terminal guidance system generates a signal indicative of the position, the terrain, and the meteorological conditions where the guidance system is located. A receiving aircraft may process the signal produced by the terminal guidance system to generate a self-contained GPS obstacle-avoidance approach path for the aircraft to the landing zone.
