Abstract:	We present a coordinate-free navigation and guidance approach that uses the location-dependent features extracted from various radio frequency signals to steer toward a destination. Unlike the conventional method, this approach does not estimate a position fix in any navigation coordinate frames. The contribution of this paper is threefold: (a) we discuss the need and motivation of the work. Our goal is to provide an alternate navigation option for circumstances when GPS signals are not available; (b) we model the system and formulate a closed loop control problem. Different types of geotag matching algorithms are proposed. This study also conducts the trade space of computational loading, trajectory length, and position accuracy by varying a number of control parameters; and (c) we demonstrate the coordinate free navigation system using simulated cellular signals, and evaluate the performance. The simulated results and analyses are presented in the paper.
