摘要
根据战略核潜艇对水下组合导航系统的战术要求及可能的配备 ,建立了 INS/ ESGM/Doppler组合导航系统的工作模式 ,推导了该组合系统的集中式 Kalman滤波算法 ,通过数字仿真将 INS/ ESGM/ Doppler组合导航系统与 INS/ ESGM组合导航系统的性能进行了详细的比较 ,说明将多普勒测速系统引入组合导航系统并应用 Kalman滤波技术 ,可有效地分别改善ESGM系统、INS系统及单纯的 INS/
According to tactical requirements and possible equipment of the stategic nuclearsubmarine on submarine integrated navigation system,this paper devises an INS/ESGM/Doppler integrated navigation system mode,and derives the centralized Kalman filter algorithm for it.Comparing the perfomance of INS/ESGM/Doppler integrated system with that of INS/ESGM integrated systemby digital simulation,it shows that introducing Doppler velocitymeasuring system into the integrated navigation system will effectively improve the precision of ESGM,INS and the integrated system combined only by INS and ESGM.
