发明名称 Method to improve carrier smoothing of code pseudorange for global positioning and GNSS receiver implementing the same
摘要 A method of smoothing a global navigational satellite system (GNSS) code pseudorange measurement included tracking first and second GNSS signals, at first and second respective frequencies, from a first satellite. A first pseudorange measurement is determined from the first GNSS signal. A smoothed pseudorange measurement is calculated from the determined first pseudorange measurement as a function of both the first and second GNSS signals. In some embodements, the smoothed pseudorange measurement is calculated from the determined first pseudorange measurement as a function of a generalized code pseudorange measurement and as a function of a generalized carrier phase measurement. At least one of the generalized code phase measurement. At least one of the generalized code pseudorange measurement and the generalized carrier phase measurement are dual frequence measurements determined as a function of both the first and second GNSS signals.
