Abstract:Through introducing the theory of configurable carrier NCO(Numerically Controlle d Oscillator) and P N code NCO, the basic structure of carrier NCO and PN code NCO is designed acco rding to the defined parameters. The result of the hardware tes t of the designed carrier NCO and PN code NCO is respectively in accordance with required parameters. Therefore,the design can be dir ectly used in the configurable navigation signal processing channel to meet the requirements for different navigation signals. It provides a solid foundation fo r further research and development of GNSS(Global Navigation Satellite System) r eceivers.
