Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A positioning system comprising one or more processors that: access ranging information, wherein the ranging information is extracted from positioning signals of a terrestrial transmitter network, and wherein the ranging information is used to measure the distance between a receiver and each of multiple transmitters in the terrestrial transmitter network; and compute an estimated position of the receiver using atmospheric assistance data from the tra…
