A FIELD TEST OF PRIMARY TRIANGULATION THEODOLITES

Abstract

A form of test of the accuracy of precision theodolites is described in which angles were measured out of doors at night with different instruments, the targets being small lights placed at about two miles from the observing station. Probable errors computed from the observations were the basis of comparison and it is shown how these were derived and employed. This test was complementary to a laboratory test on similar instruments.
