SYSTEM FOR OBTAINING LOCATION INFORMATION OF DRONE BY USING LoRa WHEN GPS RECEIVING SIGNAL OF DRONE IS ABNORMAL AND METHOD THEREOF

摘要

The present invention relates to a system for obtaining location information of a drone by using a long range wide area network (LoRa) when a GPS receiving signal of the drone is abnormal, and a method thereof. By mixing the LoRa with a location information obtaining system using a gyro/location sensor of the drone and GPS reception, the location information of the drone can be more stably obtained even in a weak propagation environment or falling. To this end, the system additionally attaches a LoRa terminal to the drone to build a drone information server through a LoRa base station when the GPS receiving signal of the drone is abnormal so as to obtain and manage the location information of the drone.;COPYRIGHT KIPO 2018
