【摘要】:針對星載全球定位系統(tǒng)(GPS)數(shù)據(jù)的特點,分別從閾值設置和周跳檢驗量的角度對Turbo Edit方法進行改進,并在傳統(tǒng)抗差估計方法的基礎上,提出一種改進的抗差估計策略。利用GRACE衛(wèi)星的星載GPS觀測數(shù)據(jù)對本文的質量控制方法進行分析驗證,結果表明:改進的質量控制方法能明顯增強周跳探測性能,有效抑制小周跳和粗差的影響,提高幾何法定軌的精度和可靠性。
[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.
