摘要
为了准确探测和修复载波相位周跳,提高定位精度,利用惯性导航器件的输出结果对接收机的运动状态进行分类,根据不同运动状态时周跳发生的概率大小,并结合高次差法和多项式拟合法的不同特点,开展了高次差法和多项式拟合法的组合应用研究.在试验研究中使用TI公司的EZ-430运动开发套件获得接收机的运动状态信息,使用Unicore UB240卫星接收机实地接收导航报文,通过试验验证,本方法可以有效地提高周跳探测的准确性并修复周跳.
In order to accurately detect and repair the carrier phase cycle slips and improve positioning accuracy, this paper used the output of inertial navigation device to classify the state of the receiver＇ s motion. According to the probability of cycle slip occurred in different motion state, combined with the different characteristics of high - order difference method and polynomial fitting method, the legitimate application of a combination of high - order difference method and polynomial fitting method was carried out. Used TI＇ s EZ -430 sports development kit to get the motion state information of the receiver, and used Unicore UB240 satellite navigation receiver to receive navigation message packages. This method can effec- tively improve the accuracy of cycle slip detection and repair cycle slips.
