A METHOD FOR DUAL-FREQUENCY IONOSPHERIC TIME-DELAY CORRECTING USING A C/A CODE GPS RECEIVER
一种利用C/A码GPS接收机实现电离层延时双频改正的方法

Ionospheric time delay is one of the largest error sources in C/A code GPS navigation and positioning. In this paper, a method is proposed for real-time dual-frequency ionospheric time-delay correcting using a C/A code GPS receiver, and the principle of the circuit block diagram for this method is analyzed with its feasibility theoretically demonstrated.
