Abstract: A method and a receiver for receiving positioning signals are disclosed. The positioning signals are received from a plurality of first sources in a first frequency range and from a plurality of second sources in a second frequency range different from the first frequency range. The receiver is switched between the first and second frequency ranges to receive the positioning signals, and the receiver obtains time offset information about a time taken to switch the receiver between the first and second frequency ranges, by obtaining a solution to a set of simultaneous equations based on combined navigation data for the first and second sources.

Abstract: A method and apparatus are presented for improving accuracy in a navigation system. A method of determining a physical characteristic of a receiving device in a navigation system, includes receiving a plurality of navigation signals from a plurality of navigation signal sources, respectively; determining a plurality of measurement estimates, based on the received navigation signals; and determining a physical characteristic of the receiving device by estimating a first set of one or more parameters in an error model, based on at least the plurality of measurement estimates. The error model includes a first error contribution for modeling noise and a second error contribution for modeling indirect signal propagation of the plurality of navigation signals.
