A pipeline deviation full-orbit fitting method of a strict regression orbit satellite can determine single-point pipeline deviation on the basis of alignment of a reference trajectory coordinate system and an orbit cutting plane according to the characteristics of a strict regression orbit, and can also perform calculation and curve fitting on data of at least one orbit. And the fitted maximum deviation is used as the pipeline deviation of the satellite, so that comprehensive analysis of strict regression precision of the satellite is carried out, limitation of single-point pipeline deviation calculation is effectively overcome, and meanwhile, the influence of single-point error data on pipeline deviation calculation can be inhibited by adopting a curve fitting method, so that the accuracy of pipeline deviation calculation is improved. And the calculation result is more accurate and reliable.
一种严格回归轨道卫星的管道偏差全轨拟合方法,能够根严格回归轨道的的特点,基于参考轨迹坐标系和切轨平面对齐来进行单点管道偏差确定,还能够对至少一轨的数据进行计算和曲线拟合,并用拟合后的最大偏差作为卫星的管道偏差,从而进行卫星严格回归精度的综合分析,并有效克服了单点管道偏差计算的局限性,同时由于采用了曲线拟合的方法能够抑制单点错误数据对管道偏差计算的影响,使得计算结果更为准确可靠。
