摘要/Abstract

摘要： 窄巷波长相对较短，受观测数据质量和未模型化误差的影响较大，导致参考站计算的窄巷FCB估值的互差较大，窄巷FCB稳定性较差。针对窄巷FCB估值出现较大偏差的参考站，本文提出了基于抗差初值的窄巷FCB抗差估计方法，该方法取当前历元所有参考站窄巷FCB估值的中位数作为抗差初值，采用IGGⅢ方案降低了有偏差的窄巷FCB估值的权比。采用IGS全球跟踪站网的数据进行验证，改进的方法提高了窄巷FCB的精度和稳定性，采用每天估计的一组卫星端的窄巷FCB即可满足窄巷模糊度固定的精度要求。同时，采用本文改进方法估计的窄巷FCB，可以提高用户端仿动态单天解的窄巷模糊度固定成功率和定位精度。

Abstract: The length of narrow-lane FCB is short, and it's seriously influenced by the quality of observation data and inaccurate models, narrow-lane FCB estimates of different reference station are significantly biased, thus the stability is relatively poor. Aiming at those biased narrow-lane FCB estimates, narrow-lane FCB robust estimation method based on robust initial value is proposed, the median of narrow-lane FCB estimates of all reference stations at current epoch is utilized as the robust initial value, and IGGⅢ scheme is applied to decrease the contribution of biased narrow-lane FCB estimates. Data from IGS global tracking stations are used in the experiment, the accuracy and stability of narrow-lane FCB are improved, the need of narrow-lane ambiguity fixing can be satisfied based on a group of daily estimated satellite narrow-lane FCB. Meanwhile, the success rate of narrow-lane ambiguity fixing and imitated dynamic positioning accuracy are improved.

Key words: narrow-lane ambiguity, fractional cycle bias, median, robust estimation, time-varying property
