摘要/Abstract

摘要： 受接收机类型、固件版本和天线的影响，GLONASS IFCB变化规律复杂且难以有效改正，导致GLONASS HMW组合包含系统性偏差，无法用于GLONASS宽巷模糊度固定。本文提出一种基于GLONASS HMW组合观测值残差的站间IFCB估计方法，并对站间IFCB变化特性进行分析。结果表明，站间IFCB长期稳定，少数相同类型硬件（包括接收机类型、固件版本和天线）站间IFCB可达0.5 m。为削弱伪距多路径效应对站间IFCB估值的影响，基于一个轨道重复周期的观测数据求得一组站间IFCB对实时观测值进行补偿，实现HMW组合平滑序列直接用于GLONASS宽巷模糊度实时固定。进行站间IFCB补偿后，基线宽巷模糊度固定正确率均在98%以上。

Abstract: GLONASS inter-frequency code biases (IFCBs) vary with receiver manufacturers,firmware versions,and antenna types.IFCBs are hardly corrected or modeled precisely,so that Hatch-Melbourne-Wübbena (HMW) combination observation contains a systemic bias and cannot applied into GLONASS wide-lane ambiguity resolution.Utilizing the residuals of GLONASS HMW combination observations,we propose an algorithm to estimate IFCB of different sites (DS-IFCB).The experiment results show that DS-IFCB is long term stability and the sizes of DS-IFCBs in some homogeneous baselines (composed by same type of devices,i.e.receiver type,version and antenna) are larger than 0.5 meters.In order to achieve wide-lane ambiguities in real-time,DS-IFCBs,estimated with previous observations,are used as priors to cancel IFCBs in current observations.After DS-IFCB offset,both the success rate and correct rate of GLONASS wide-lane ambiguity resolutions are improved,regardless of whether baselines are equipped with homogeneous devices.The correct rates of all baselines are higher than 98%.

Key words: GLONASS, HMW combination, IFCB, wide-lane ambiguity resolution
