摘要
针对北斗卫星导航接收机在复杂电磁环境下定位能力不足等问题,提出一种基于北斗周跳检测与修复自回归的定位方法,构建了联合周跳检测模型,并通过数理统计方法实现了周跳的自主修复。通过实验证明,所提方法实际周跳修复值与真实值之间的误差控制在0.2周,定位精度达到3.5 m,有效提升了周跳检测精度和定位精度。
A positioning method based on Beidou cycle slip detection and repair autoregressive is proposed to address the problem of insufficient positioning capability of Beidou satellite navigation receivers in complex electromagnetic environments.A joint cycle slip detection model is constructed,and autonomous repair of cycle slips is achieved through mathematical and statistical methods.Through experiments,it has been proven that the proposed method controls the error between the actual cycle jump repair value and the true value within 0.2 cycles,and achieves a positioning accuracy of 3.5 m,effectively improving the cycle jump detection accuracy and positioning accuracy.
