Abstract
The present invention relates to a system for improving accuracy and safety of UAV navigation, and for generating an optimal protection level and geometry screening, and more particularly to a system that monitors an error and a failure of a GNSS navigation signal, broadcasts error correction information and integrity information to a UAV within a radius of about 20 km to allow the UAV to apply the corresponding information by a ground module, thereby improving the navigation accuracy and safety of the UAV. The ground module receives a GNSS navigation signal, calculates GNSS navigation error information, and generates correction information, and monitors a failure through a simplified failure monitoring algorithm, and the mounted module provides a system and a method for receiving a message that is broadcast by the ground module, and calculating precise and safe navigation information of an UAV by applying the message.
