SIMULTANEOUS GEODIMETER AND TELLUROMETER DISTANCES

Meteorological effects on electronically measured distances depend on the carrier wavelength. Distances were measured simultaneously with the Geodimeter 8 and the Tellurometer MRA3 MkII, and three distance reduction methods applied: (1) The conventional correction procedure; (2) a procedure derived by using differences between lightwave and microwave distances; and (3) one derived by using simultaneous reciprocal zenith distances. The results indicate that the two unconventional procedures are superior to the conventional one. Advantages and disadvantages of the procedures are examined.
