摘要: 电离层传播延迟是C/A码GPS导航定位的主要误差源之一。本文提出了一种利用C/A码GPS接收机实现电离层延迟实时双频改正的方法,并对实现这一方法的电路框图的原理进行了分析,从理论上说明了其可行性。Abstract: 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.
