Abstract: | The satellite navigation signal measuring technique is the core content of measuring stations of a navigation system.This paper introduces the navigation signal measuring technique which has a better real-time performance,a higher processing accuracy and a better reliability.Then the real-time observation data and navigation signals,which are exported from the measuring receiver,are analyzed and processed.The rationality,quality and positioning precision are analyzed.In the meantime the original data are exported.By means of the distance measuring and equipment delay measuring realization,the measuring station can achieve Two Way Satellite Transfer Time(TWSTT) along with the navigation system,and the error of TWSTT is less than 3ns. |
