由于潜艇导航误差随时间增长不断积累,潜艇需要在一定时间内潜出水面短暂时间,以接收外部的卫星导航定位信息,以此来修正导航误差。另一方面,在惯性导航设备需要水面航行状态下完成海上启动时,也需要接收外部的位置信息进行辅助动态对准。本文以潜艇浮出水面时接收GPS(北斗)校正信息为背景,通过Matlab软件仿真其遇到干扰时的导航情况,利用GPS(北斗)信号的残差χ2检验法检测和剔除GPS(北斗)信号中的坏值信息,保证了潜艇在复杂战场电磁环境下的重调的有效性、可靠性。
As the navigation error is accumulating over time, submarines are required to dive out of the water for a short time within a few days to receive external information of satellite navigation and positioning service so that they can modify the navigation error. In addition, when the inertial navigation equipment needs to start in the state of surface navigation, they still need to receive the information from an external location-aided dynamic alignment system. Through the stimulation of the process of navigation when it encounters interference using MATLAB, this project is set in the background of receiving GPS (Beidou) correction information when the submarine emerges and guarantees the safety and reliability of submarine reset navigation under complicated electromagnetic environment using residual test method of GPS (Beidou) signal to detect and eliminate the bad value in the GPS (Beidou) signal.
