Multipath influence on code range under static condition is described firstly in this paper, and the problem that to what
extent the phase-aided smoothing can mitigate multipath interference is detailed. Some problems regarding smoothing and mitigation
are discussed. Suggestions based on the analysis has been made.

地基GPS遥感大气水汽含量的误差分析 总被引:35,自引:2,他引:35
讨论并分析了利用地基GPS遥感大气水汽含量时的误差源及其数值评估。其误差来自三个方面:一是计算GPS讯号传输时间中湿延迟的误差;二是将该湿延迟转换为大气水汽含量公式中测定转换因子的误差;三是转换模型的误差。 相似文献

本文介绍了应用彩红外航片对城市居民生活条件进行调查和分析,其基本方法是:首先通过直接和间接判读标志,对居民物质生活条件和精神生活条件进行解译,然后从方便度和舒适度两项评价指标入手,选取八项评价因子,进行定量的综合评价和空间分析,最后提出改善实验区居民生活条件的建议。 相似文献
