利用样条分频消除GPS与APS组合定位中海浪扰动的方法研究

Research of Sea Wave Disturbances Reduction in GPS/APS Combined Positioning by Spline Separating Signals Method

在GPS/APS组合定位技术实际应用中,由海浪引起的测量基准起伏会对定位结果数据产生较大波动,针对这一问题,引入了样条分频方法,进行了算法设计,利用实测数据进行了仿真分析,结果表明:该方法可以实现对混合于测量信号中的非被测目标位置特性信号的分离,在数据处理中能有效消除海浪对定位数据的影响。

In the application of the combined positioning of GPS/APS, the sea wave caused benchmark undulation will produce great fluctuation in the result data. To solve this problem, an arithmetic model is designed based on the spline separating signals method. The simulation analysis using real measured data shows that the method can separate non-meas- ured object＇s position characteristic signal from the measured signal, and the sea wave influ- ence can be effectively reduced in data processing.
