摘要
指出文献［１］、［２］、［３］、［４］中计算多航向航行时的推算船位标准误差圆半径的公式ρ＝ρ１＋ρ２＋…＋ρｎ是错误的，并且证明推算船位标准误差圆的正确计算公式为ρ＝ρ２１＋ρ２２＋…
This paper points out that in ,,, the calculation formula of error circle radius of estimated position when sailing by more courses is incorrect. And it proves that the calculation formula of error circle radius of estimated position is ρ=ρ 2 1+ρ 2 2+…+ρ 2 n .
