摘要
本文利用中国地壳运动观测网络的GPS数据,兼顾卫星发射频率硬件延迟影响,模拟了BD-2系统的电离层VTEC,并建立GPS/BD-2组合系统的VTEC格网模型,实验结果证实了该模型在电离层延迟短时间预报上的有效性。
Considering the delay of satellites＇ sending frequencies,the authors simulated the ionospheric VTEC of BD-2 with GPS data of the Crustal Observation Network of China（COMNOC）,and established the VTEC grid model of GPS/BD-2 combined system.The experiment results showed the validity of this model in short-term forecast of ionospheric delay.
