depthometer造句

As the traditional navigation system ca n ' t satisfy the requirements of the autonomous underwater vehicles ( auv ) navigation and position . we study a depthometer - doppler - aided strapdown inertial navigation system ( ddsins ) in combination of the developments of periodic navigation technique and some practical problem posed by the mathematical and variation of output data of doppler , furthermore , the digital simulation and semiphysica test are made to verify the validity of the algorithm , the main research work are as follows : design of the strapdown inertial navigation system of auv
由于传统的导航系统很难满足远程水下航行器精确导航、定位的要求，本文在充分考虑使用特殊性的情况下，结合国内、外导航技术发展的实际状况和发展方向，研究了水下航行器组合导航系统的误差，重点解决了因多普勒输出数据周期长和周期时变而给导航计算和滤波器设计带来的问题，并进行了仿真和实物测试，仿真和实物测试结果表明本文所研究的设计方案合理，可以达到某型水下航行器导航、定位需要的精度。
