【摘要】：隨著北斗導(dǎo)航系統(tǒng)的日益發(fā)展，iGMAS應(yīng)運(yùn)而生。iGMAS譯為國際全球連續(xù)監(jiān)測評估服務(wù)，，其服務(wù)功能與IGS（international GNSS Service，國際GNSS服務(wù)）相同，旨在為全球用戶提供導(dǎo)航數(shù)據(jù)與精密產(chǎn)品。主要區(qū)別在于IGS僅提供GPS、GLONASS系統(tǒng)的數(shù)據(jù)與產(chǎn)品，而iGMAS可提供四系統(tǒng)（GPS、GLONASS、BDS、Galileo）的數(shù)據(jù)。 北斗ICD文檔的發(fā)布，帶動(dòng)了iGMAS芯片以及接收機(jī)的研發(fā)。而iGMAS接收機(jī)能否提供正常的定位服務(wù)，取決于其數(shù)據(jù)質(zhì)量。 基于以上戰(zhàn)略需求，本文承擔(dān)了幾款iGMAS接收機(jī)比測的任務(wù)，即對實(shí)測iGMAS數(shù)據(jù)進(jìn)行質(zhì)量分析，定位解算，判斷其是否能滿足基本的服務(wù)。本文主要針對以下兩點(diǎn)做了研究： （1）數(shù)據(jù)質(zhì)量分析 數(shù)據(jù)質(zhì)量分析包括數(shù)據(jù)完好性、多路徑、周跳。本文研究了周跳探測、多路徑計(jì)算的方法。對實(shí)測的GPS、GLONASS數(shù)據(jù)使用TEQC軟件進(jìn)行了質(zhì)量分析，BDS數(shù)據(jù)使用筆者改進(jìn)后的BNC軟件進(jìn)行質(zhì)量分析。 （2）定位解算 定位解算包括非差精密單點(diǎn)定位與雙差相對定位。本文研究了這兩種定位的方法，并對實(shí)測數(shù)據(jù)進(jìn)行了解算，從內(nèi)符合精度與外符合精度兩方面對結(jié)果進(jìn)行了評估。定位軟件使用Bernese5.0。 本文的主要貢獻(xiàn)： 對開源軟件BNC進(jìn)行了改進(jìn)，使其可以識別BDS、正確讀取BDS數(shù)據(jù)和廣播星歷，可計(jì)算三頻數(shù)據(jù)，可計(jì)算每顆星的多路徑值，可計(jì)算GEO衛(wèi)星位置，最終分析BDS的數(shù)據(jù)質(zhì)量。
[Abstract]:With the increasing development of the Beidou navigation system, iGMAS.IGMAS came into being for the international global continuous monitoring and assessment services, the service function and IGS (International GNSS Service, international GNSS service), in order to provide navigation data and precision products for users worldwide. The main difference is that IGS only provides GPS data and products of GLONASS system, and the iGMAS can provide four systems (GPS, GLONASS, BDS, Galileo) data.
The release of the Beidou ICD document has led to the development of the iGMAS chip and the receiver, and whether the iGMAS receiver can provide a normal positioning service depends on the quality of its data.
Based on the above strategic requirements, this paper has undertaken several tasks of iGMAS receiver, which are quality analysis of measured iGMAS data, location and calculation to determine whether it can meet the basic services.
(1) data quality analysis
The quality of data analysis including data integrity, multi path, cycle slip. This paper studies the cycle slip detection method, multi path calculation. The measured GPS, GLONASS data quality analysis using TEQC software, BNC software BDS data using the improved quality analysis.
(2) location calculation
The location solution includes non differential precise point positioning and double difference relative location. In this paper, the two positioning methods are studied, and the measured data are calculated. The results are evaluated from the two sides of the internal coincidence accuracy and the external coincidence accuracy. The location software is Bernese5.0..
The main contributions of this article are:
The open source software BNC is improved, which can identify the BDS, read BDS data and broadcast ephemeris, calculate the triple frequency data can be calculated, multiple paths of each star, can GEO satellite position calculation, the final analysis of the data quality of BDS.
