SYSTEM FOR GUIDING AUTONOMOUS LANDING OF UNMANNED AERIAL VEHICLE DURING EMERGENCY MANEUVERING DEPLOYMENT AND GUIDING METHOD

A system for guiding autonomous landing of an unmanned aerial vehicle during emergency maneuvering deployment and a guiding method. The guiding system comprises a plurality of ground guiding stations and an on-board guiding terminal. Each ground guiding station establishes ad hoc network data link communication with the on-board guiding terminal. The on-board guiding terminal transmits application signals to the ground guiding stations, receives response signals from the ground guiding stations, measures the bidirectional distance between the on-board guiding terminal and the plurality of ground guiding stations, simultaneously receives elevation information, calculates position information of the on-board guiding terminal, and sends the position information to an unmanned aerial vehicle flight control system for unmanned aerial vehicle landing guidance. By using elevation information as a positioning calculation constraint condition, positioning accuracy is increased when an unmanned aerial vehicle is far aw
