On the Statistical Characteristics of the Residual in Time-Based Position Location Systems

Jeannette Nounagnon

Abstract:	Geolocation accuracy is a very crucial and a life-or-death factor for rescue teams. Natural or man-made disasters, are just a few convincing reasons why fast and accurate position location is necessary. Recently, geolocation using GPS has been integrated into regular daily applications, such as location-aware advertising, surveying or agricultural activities. The need for accurate geolocation estimates is vital for the betterment of our communities. This paper introduces a novel upper bound to the mean square error (MSE) of position error in a time of arrival geolocation system. The novel aspect of this work lies in the establishment of a closed-form expression for the upper bound on MSE of position error based on the expected value of the residual. This work investigates one facet of the residual, by relating residual to position error.
