Urban Positioning using Signals of Applicability

Greg Gerten

Abstract:	Navigation has become a billion dollar industry but users in large metropolitan areas are becoming discouraged over lack of availability and accuracy in areas where the majority of the population reside. This paper will discuss methods to use all signals of opportunity to assist and be used in the solution filter. With the explosion of location based services (LBS) users are seeking methods to provide them with position information in the toughest of environments (urban canyons, indoors, etc.). We will demonstrate methods that can be used to mix and match different sources of information to provide position, velocity, and time (PVT) data to the user by using existing signals and sensors. These pieces of data will be combined in a filter to provide the user with PVT data and a measure of how good that solution is by incorporating covariance data. Therefore the outcome will be the capability for millions of users to have confidence that they will now have PVT anywhere anytime
