Abstract: Determining if a receiver is inside or outside a building or area. Particular systems and methods for determining if a receiver is inside or outside a building determine an estimate of a position of a receiver, and use the estimate of the position of the receiver and other data to determine if the position of the receiver is inside a first building. The other data may include locations of geo-fences inside buildings, heights of buildings, or other types of data.

Abstract: Systems and methods are described for determining position of a receiver. The positioning system comprises a transmitter network including transmitters that broadcast positioning signals. The positioning system comprises a remote receiver that acquires and tracks the positioning signals and/or satellite signals. The satellite signals are signals of a satellite-based positioning system. A first mode of the remote receiver uses terminal-based positioning in which the remote receiver computes a position using the positioning signals and/or the satellite signals. The positioning system comprises a server coupled to the remote receiver. A second operating mode of the remote receiver comprises network-based positioning in which the server computes a position of the remote receiver from the positioning signals and/or satellite signals, where the remote receiver receives and transfers to the server the positioning signals and/or satellite signals.

Abstract: Calibrating an unstable sensor of a mobile device. Systems and methods for calibrating a sensor of a mobile device determine a first estimated position of the mobile device without using any measurement from the sensor of the mobile device, generate a second estimated position of the mobile device using a measurement from the sensor, estimate a sensor error of the sensor using the first estimated position and the second estimated position, and use the sensor error to determine a calibration value for adjusting one or more measurements from the sensor.

Abstract: Determining building weather profile parameters, and correcting an estimated altitude of a receiver using the building weather profile parameters. Systems and methods for estimating an altitude of a receiver using building weather profile parameters may identify one or more weather profile parameters for a building, determine an initial estimate of a receiver's altitude at a floor inside the building, and use the initial estimate and the identified weather profile parameters to determine a corrected estimate of the receiver's altitude at the floor.

Abstract: Devices, systems, and methods for gathering, calculating and sending positioning information at a user device to one or more networks. In a first implementation, a user device transforms pseudorange information relating to terrestrial beacons into GNSS pseudorange information. In a second implementation, a user device sends position information using GNSS information elements. In a third implementation, a user device sends position information using non-GNSS information elements.
