In some parts of the coloured band they are positively crowded together, sharp and fine, like the spider lines of a macrometer, from which an uninitiated eye might easily not distinguish them. |
Both model macrometer surveyors use the same unique antenna which virtually eliminates the multipath problem experienced by the Doppler satellite receivers. |
The macrometer contains an electronic solid state memory where the satellite signals are recorded on a cassette which can be sent to the Base Station for further processing. |
The macrometer determinations of the distances between the four closely spaced test points differed from the previous conventional determinations by 4 mm in the worst case.
