The Measurement and Time Series Analysis of Loran C Ground Wave Propagation Delay

Abstract:

In order to effectively correct the positioning error of Loran C to improve the positioning accuracy, it is necessary to study Loran C ground wave signal propagation delay variation with time, study the stability of propagation delay and timing characteristics. Take statistical analysis and pretreatment to Loran C ground wave signal propagation delay, test its stationarity, extraction its trend term, obtain stationary series, modeling to trend term and stationary series. The results show that Loran C ground wave signal propagation delay has good stability and repeatability, the time delay series can be fitted to combination model formed by G (2,1) cycle model and AR (p) from the regression model.
