The accuracy of a Loran sky wave line of position depend chiefly upon the accuracy of matching and reading the signal on receiver-indicator, the accuracy of the sky wave correction and the geometrical factor of precision. We discussed the accuracy of matching sky wave by many observations and found that the influence on the accuracy of a position line is not so large compared with the other two effects. The distributions of the probable error of practical Loran sky wave position line about the several Loran pair at north pacific are calculated. The sky wave accuracy patterns are also shown. From these patterns, the navigator can see the accuracy of a Loran sky wave posision line at once.
