- W40645905 abstract "본 논문은 RLG의 신호처리 기법인 Trapping 기법 적용시 각속도와 가속도의 측정시점 불일치에 의해 발생되는 오차를 보상하는 기법에 관한 연구이다. RLG의 대표적인 신호처리 기법인 Stripping 신호처리 기법과 Trapping 신호처리 기법에 대하여 각 기법의 오차요인을 분석하고 이에 대한 모델링을 수행하였다. 그리고 Trapping 기법 적용시 각속도와 가속도 측정시점 불일치에 의해 발생되는 오차에 대한 모델링을 통하여 항법오차에 미치는 영향을 분석하였으며 이를 감소시키기 위한 새로운 신호처리 기법을 제안하고 시뮬레이션 및 시험을 통하여 이에 대한 성능분석 결과를 제시하였다. 성능 분석결과 본 논문에서 제시한 신호처리 기법이 기존의 방법에 비하여 항법오차를 크게 감소시키는 것을 확인할 수 있었다. In this paper, we propose the new method to decrease the navigation error by measurement time synchronization error in RLG Trapping signal processing. There are two methods to eliminate the dither motion in RLG. One is the stripping signal processing method. Another is the trapping signal processing method. This two methods have various error sources in measurement output. We perform the error modelling and analysis for the measurement time synchronization error between angular rate from RLG and acceleration from accelerometer in the trapping signal processing method. And we verify the navigation performance through simulation and experiment. Results of simulation and experiment show that the proposed method is very effective in decreasing the navigation error." @default.
