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: A method for generating and transmitting positioning signals using a network of terrestrial beacons, comprising generating, at a first beacon, a first positioning signal using a first pseudorandom number sequence, generating, at a second beacon, a second positioning signal using a second pseudorandom number sequence, broadcasting the first positioning signal during a first time slot of a transmission frame, and broadcasting the second positioning signal during a second time slot of the transmission frame.
