Claim Text:
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 transmitters, atmospheric data from one or more atmospheric sensors at the receiver, and at least one of the ranging information and information extracted from signals of a satellite positioning system, wherein the estimated position is computed during an operating mode, wherein the operating mode is a first operating mode during which at least one position coordinate of the estimated position is computed by at least one processor at the receiver, or a second operating mode during which the at least one position coordinate of the estimated position is computed by at least one processor at a server.
