With the development and perfect of GPS,the technic of RTK is more and more widely used.The differential data transmission is the key point in it.We can enlarge the range of mapping region by utilizing CDMA wireless data transmission in transporting GPS difference data,and realize high precision orientation of real time.This article introduced the basic principle of RTK technic,and give the analysis of the system constructure and main functions of RTK differential data transmission technic which is based on CDMA.Further more,we made a discussion on designing of mobile station software.
