【摘要】:针对姿态测量基于短基线精密相对定位,而观测值的周跳直接影响基线解算精度,将导致姿态解算结果数据质量下降的问题,提出了姿态测量应用中的周跳组合探测修复方法。文章在分析姿态解算原理及误差影响程度的基础上,结合经典电离层残差法和多项式拟合法,探讨其在北斗卫星导航系统中周跳探测修复的方法原理、缺陷及对北斗数据探测修复效果,结合实际情况提出了姿态测量应用中的组合探测修复方法。采集真实数据实时解算,定量计算了修复后的基线解算精度和姿态测量效果,验证了所提出的方法可用于实际测量解算,处理后的姿态测量精度满足使用需求,研究结果对北斗姿态解算有参考价值。
[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.
