| Abstract: | The program selection and implementation of phase helicase(carrier strip) affects the baseband signal processing and the stability and accuracy of position resolution greatly in GPS and GLONASS satellite navigation receiver.General phase helicase program can not meet the actual situation of the combo receiver.According to the principle of phase helicase and the practical problems of the combo receiver,the complex phase helicase program is selected,and improvements are achieved in particular in its structure... |
