【摘要】：针对星载全球定位系统(GPS)数据的特点,分别从阈值设置和周跳检验量的角度对Turbo Edit方法进行改进,并在传统抗差估计方法的基础上,提出一种改进的抗差估计策略。利用GRACE卫星的星载GPS观测数据对本文的质量控制方法进行分析验证,结果表明:改进的质量控制方法能明显增强周跳探测性能,有效抑制小周跳和粗差的影响,提高几何法定轨的精度和可靠性。
[Abstract]:According to the characteristics of spaceborne global positioning system (GPS) data, the Turbo Edit method is improved from the point of view of threshold setting and cycle slip test. Based on the traditional robust estimation method, an improved robust estimation strategy is proposed. The quality control method of this paper is analyzed and verified by using the spaceborne GPS observation data of GRACE satellite. The results show that the improved quality control method can obviously enhance the performance of cycle slip detection and effectively restrain the influence of small cycle slip and gross error. Improve the accuracy and reliability of geometric rail.
