碩士 === 義守大學 === 電機工程學系 === 105 === With the rapid development of portable mobile devices and tendency of everyone owning a mobile phone in recent years, users can use GPS outdoors to quickly know where he is, but in modern areas, having tall building around, or indoors, satellite signals are easily to be blocked which will affect GPS and cause over-15-meter plane error or be impossible to locate. Using the distributional property of Wi-Fi signal sent by the router, this thesis solves the problem of GPS unable to locate indoors via Wi-Fi signal by differentiating different sources and strength of Wi-Fi received indoors and making a positioning judgment of mobile device staying indoors. This thesis uses Arduino TIAN as the main core of receiving Wi-Fi signals'' processing and operation and UAV’s motions, and compares different Wi-Fi signals sent by multiple routers in the laboratory, so that UAV can make positioning judgment right away even indoors reaching the aim of preventing UAV from running into a brick wall due to the improper operation when flying indoors. UAV was used for military purpose in the old times. Most recently, UAV becomes a good seller among the consuming users because of many factories opening the technique for UAV and every people can get the UAV with a low price. This research can be applied to a wide range of technique aspects to quickly solve the problem, no matter for military use or disaster relief in order to saving the labor and time and also making significant changes and renovations for the future life.
