摘要
近年来,雾霾现象呈现频率增多、程度增大的趋势,GPS信号在穿越发生雾霾的区域上空时,是否会受到影响,本文就雾霾天气(空气质量)对GPS定位产生的影响做出了初步探索,研究得出雾霾(空气质量)与天顶对流层延迟的湿分量延迟有正相关关系,但对多路径效应以及精密单点定位精度没有影响,且定位时可以不考虑雾霾带来的影响。
In recent years,the frequency of fog and haze weather shows a rise tendency. When GPS signal crosses the haze sky region,it will be affected or not. The paper preliminary explores the impact of fog and haze weather on GPS precise point positioning. The results show that the haze-index（ air quality）and wet component of tropospheric propagation delay has positive correlation,but it has no effect on the multipath and accuracy of precise point positioning. GPS precise point positioning does not need to consider the influence of haze.
