构建阈值模型改善TurboEdit实时周跳探测
|
Abstract:
在比较现有各类TurboEdit改进算法的基础上，选取了一套适合实时周跳探测的组合方法，并针对其缺陷进行优化改进，加入阈值模型。在滑动平均滤波MW（Melborne-Wubbena）组合周跳探测方法中加入了自适应观测序列均方根变化的阈值模型，有效减少了周跳探测的误判和漏判；在相邻历元求差的GF（geometry-free）组合周跳探测中加入了随采样率及卫星高度角变化的加权阈值模型，显著提升了采样率较低时周跳探测的可靠性。大量数据测试检验表明，该组合方法有效可行，相比其他改进方法不仅在探测精度上有一定提高，在避免周跳误判、漏判上也有较大改善
