【摘要】：針對姿態(tài)測量基于短基線精密相對定位,而觀測值的周跳直接影響基線解算精度,將導(dǎo)致姿態(tài)解算結(jié)果數(shù)據(jù)質(zhì)量下降的問題,提出了姿態(tài)測量應(yīng)用中的周跳組合探測修復(fù)方法。文章在分析姿態(tài)解算原理及誤差影響程度的基礎(chǔ)上,結(jié)合經(jīng)典電離層殘差法和多項(xiàng)式擬合法,探討其在北斗衛(wèi)星導(dǎo)航系統(tǒng)中周跳探測修復(fù)的方法原理、缺陷及對北斗數(shù)據(jù)探測修復(fù)效果,結(jié)合實(shí)際情況提出了姿態(tài)測量應(yīng)用中的組合探測修復(fù)方法。采集真實(shí)數(shù)據(jù)實(shí)時解算,定量計算了修復(fù)后的基線解算精度和姿態(tài)測量效果,驗(yàn)證了所提出的方法可用于實(shí)際測量解算,處理后的姿態(tài)測量精度滿足使用需求,研究結(jié)果對北斗姿態(tài)解算有參考價值。
[Abstract]:Aiming at the problem that attitude determination is based on the precision relative positioning of short baseline, and the cycle slip of observation value directly affects the accuracy of baseline calculation, which will lead to the deterioration of the data quality of attitude resolution results, a combined cycle slip detection and repair method in attitude determination application is proposed.On the basis of analyzing the principle of attitude calculation and the degree of error influence, combined with the classical ionospheric residual method and polynomial fitting method, this paper discusses the principle of the cycle slip detection and repair in Beidou satellite navigation system.Defect and effect of Beidou data detection and repair, combined with the actual situation, the combined detection and repair method in attitude measurement application is proposed.The real time calculation of real data is obtained, and the accuracy of baseline calculation and attitude measurement are calculated quantitatively. It is verified that the proposed method can be used in actual measurement and calculation, and the precision of attitude measurement after processing can meet the needs of application.The results are valuable for the calculation of Beidou attitude.
