[0002] In today's era of rapid technological advancement, unmanned aerial vehicle (UAV) technology has demonstrated enormous application potential in numerous fields, especially solar-powered UAVs. With their sustainable energy acquisition methods and unique flight performance, they are gradually emerging and gaining widespread attention and application in both military and civilian sectors, such as meteorological monitoring and communication platforms. In the field of meteorological monitoring, solar-powered UAVs can cruise over specific airspaces for extended periods, accurately collecting various meteorological data, such as changes in atmospheric temperature, humidity, air pressure, and wind speed and direction.
