| Abstract: | Pointing at the meteorological correction formula of the DI2002 laser range finder, connecting with the characters of the seismological monitoring and the meteorological element observation of precise distance measurement at present in China, and based on the discussion of the basic meteorological correction of the electromagnetic ranging, the precision meteorological correction formula of the DI2002 laser range finder is deduced. The result shows that, comparing with the formula in the technical manual of instrument, the presented formula not only gives the higher precision of meteorological correction calculating, but also suits to the observation of different meteorological elements, so it has general practical significance. At last, the effects of the every meteorological element observation error on the results of the DI2002 laser range finder are systematically analyzed. The error of the every meteorological element in choosing meteorological reference point is calculated quantitatively and its dynamic trend is analyzed, which have an important significance for controlling meteorological element observation error and effectively alleviating the influence on result of the distance measurement. |
