Abstract: Techniques are provided which may be implemented in an electronic device to establish certain enhanced database information for point locations which may correspond to an estimated location of a mobile device. For example, some enhanced database information may be based, at least in part, on a satellite signal visibility mask. All or part of such enhanced database information may be provided to one or more mobile devices, which may use the enhanced database, at least in part, for location estimation.

Abstract: Disclosed are methods, systems and devices for providing location based services in a venue. To estimate its location, in a particular implementation, a mobile device may obtain a measurement of a range to a transponder device positioned at a known location based on measurements of a signal round-trip time (RTT) in a message exchange with the transponder device. Positioning assistance data from a server may enable the mobile device to measure a delay at the transponder device in providing a response to a probe message to thereby more accurately measure the signal RTT.

Abstract: Systems, methods and devices for improving the accuracy of GNSS data are provided. Specifically, embodiments of the invention can advantageously use sensor input to improve the accuracy of position fixes. The use of physical 5 sensors in navigation systems is deemed particularly advantageous, especially where altitude data derived from the pressure sensor is calibrated with and/or blended with GNSS altitude data.

Abstract: Systems, apparatus and methods for populating and using a pressure database to determine an altitude of a unit with an unknown altitude are presented. A pressure from one or more barometric pressure sensors linked to respective base stations are interpolated to determine a reference pressure (e.g., at sea level) at arbitrary coordinates (x,y) having pressure reading. For example, a mobile station at the arbitrary coordinates (x,y) records a pressure at the mobile station. A difference between this pressure at the mobile station and the interpolated reference pressure is determined, which may directly be interpreted as a defined altitude of the mobile station.
