This paper presents a fully functional and highly portable mini Unmanned Aerial Vehicle (UAV) system, HAWK, for conducting aerial localization. HAWK is a programmable mini helicopter -Draganflyer X6 -armed with a wireless snifferNokia N900. We developed custom PI-Control laws to implement a robust waypoint algorithm for the mini helicopter to fly a planned route. A Moore space filling curve is designed as a flight route for HAWK to survey a specific area. A set of theorems were derived to calculate the minimum Moore curve level for sensing all targets in the area with minimum flight distance. With such a flight strategy, we can confine the location of a target of interest to a small hot area. We can recursively apply the Moore curve based flight route to the hot area for a fine-grained localization of a target of interest. Therefore, HAWK does not rely on a positioning infrastructure for localization. We have conducted extensive experiments to validate the feasibility of HAWK and our theory. A demo of HAWK in autonomous fly is available at

“…Recently, WiFi-enabled mobile devices (e.g., mobile phones, music players, or digital cameras) have become very popular, and WiFi access points (APs) abound in most urban areas. Using this infrastructure, various kinds of WiFi-based location estimation techniques have been proposed [14].There are three well-known methods for location estimation using WiFi-based wireless signals: RSSI, TOA, AOA methods.…”

Location-aware systems for short-range wireless networks, also called indoor positioning systems (IPSs), have become considerably popular in recent years with rapid evolution of ubiquitous computing and short-range wireless communications technologies. Much research and commercial IPSs have been developed and many of them have been applied or may soon be adopted in wide domains, like asset and people tracking, healthcare, manufacturing, safety, retail and shopping etc. In this paper, we present a layered conceptual framework of IPSs. Furthermore, a classification of current typical IPSs is introduced. Based on this classification, we discuss various existing IPSs focusing on positioning technical points, applications and analyse possible opportunities and challenges in the future.
