Receiving positioning signals at different frequencies
First Claim
1. A method for receiving positioning signals from a plurality of first sources in a first frequency range in a receiver, the method comprising the steps of:
- receiving signals in a second frequency range different from the first frequency range;
receiving positioning signals from a plurality of second sources in the second frequency range at the receiver;
calculating time offset information related to a switching time taken to switch the receiver between the first and second frequency ranges; and
compensating for the switching time, based on the calculated time offset information.

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.
