| 摘 要： | 连续旋转式寻北仪以其突出的性能成为当前寻北仪研究的热点,但关于转台误差对连续旋转寻北算法精度影响的分析很少.针对速率偏频激光陀螺寻北仪,研究了转台测角周期性误差对寻北结果的影响.理论分析表明,测角周期性误差的存在会导致寻北结果偏离真实值,必须对其进行建模和补偿以提高寻北精度.对理论分析结果进行了仿真实验和样机寻北实验验...

| Abstract: | Currently,the continuous rotary north-finder is widely discussed for its outstanding performance.However,few researches about the influence of turntable error on the continuous rotary north-finding algorithm can be found.For the north-finder based on rate biased RLG(ring laser gyro),the influence of turntable's periodic angular position errors to the north-finding results was studied.Theoretical analysis shows that,the existence of periodic angular position errors may cause unexpected error in the north-fin... |
