Abstract
Systems and methods of precision landing in adverse conditions are provided. In one embodiment, a precision landing system comprises a vehicle including: a receiver configured to receive position information for structures and a landing zone of a landing site and a processor coupled to a memory, the memory includes three-dimensional geometric structural information for a landing site. The processor configured to: receive the position information from the receiver; assign geographical coordinates to the three-dimensional geometric structural information using the position information for the structures and the landing zone of the landing site; send the three-dimensional geometric structural information and graphical rendering information to a display device. The vehicle further includes a display device, wherein the display device is configured to render and display a three-dimensional representation of the landing site in real-time based on the three-dimension geometric structural information and the graphical rendering information from the processor.
