俯仰扰动 meaning in Chinese

pitch disturbance

Thirdly , based on the thought of motion - based ambiguity resolution , a bi - satellite attitude determination method using non - planar baselines is developed making full use of the satellites ’ geostationary property . focused on movement mode demands , the dissertation brings forward a method by large angle yawing movement accompanied with small angle pitch vibration to efficiently solve the rank deficiency problem of vehicle planar motion
再次,在基于运动解模糊的思想基础上,充分利用北斗卫星对地静止的特性,提出了一种非共面基线的双星定姿方法,并重点分析了对运动特性的要求,提出通过伴随小幅俯仰扰动的大角度偏航运动方式来有效解决载体平面运动的观测矩阵秩亏问题。
The mathematical simulation results indicate that the above developed method can realize ambiguity initialization within 30 seconds ( 1hz data rate provided ) with above 97 percent success rate as long as the pitch angle motion magnitude of vehicle is not less than 5 , and yield real time attitude resolution precision of 0 . 0742 in yaw , 0 . 0671 in pitch , and 0 . 0867 in roll using the antennae array with
数学仿真实验表明:当俯仰扰动幅度不小于5时,可在30s ( 1hz采样率)内以97 %的成功率实现双星定姿模糊度初始化,并且利用5m基线可达到偏航0 . 0742 、俯仰0 . 0671 、滚动0 . 0867的实时姿态解算精度。
