Introducing New Localization and Positioning System for Aerial Vehicles

The concept of localization and positioning has received major attention as the use of UAVs is growing by day. Although there is the general method of GPS for positioning, as we will explain later, the need for alternative measures, such as new methods of localization based on visual means are growing. In this letter we present a new system based on common ubiquitous wireless and communication transmitters, presenting a new localization method based on Multilateration through calculations of time difference of arrival (TDOA) of the propagated signals. In this system we will, so to speak, turn the GPS system upside down and instead of using satellites as reference points in our positioning calculations, we will use the common stationary transmitters; making this system a perfect alternative for GPS and other visual based positioning systems.
