Application Research Of Precision Azimuth And Elevation Transfer Method

The implement of measurement methods are inseparable with measurement instruments.Measuring instruments improvement or technology innovation is both developed around how toreduce the measurement error and then to improve the measurement accuracy. But no matter howprecision instrument manufacturing, in the measurement of the surveying process, themanufacturing errors and the effects of external conditions are inevitable. According to theanalysis of measurement errors, put forward some kind of methods to eliminate or to weaken theinfluence of surveying errors and ensure the accuracy of the measurement is the focus of theresearch. In this paper, combined with the practical working and the new improvement ofSurveying equipment, the author raises a series of precision azimuth and elevation transmissionmeasurement methods in order to obtain high precision azimuth and elevation data.The main content of this paper is to analysis the effects of the measurement errors and inthis foundation to propose the precise azimuth measuring and precise elevation transmittingmethod. The main contents are as following:â'ˆThis study introduces the total station angle and distance measurement principle anderror correction technology and analyses the total station angle ranging error and correctapplication of error correction technology mode.â'‰According to the examples of measurement comparison and analysis of differentmethods, This paper analyzes the short edge azimuth transfer error and studies the application ofthe precision total station with short distance azimuth transfer measuring method.â'ŠIn this paper, the digital leveling system in elevation transmission error and the specialelevation transmission technology and methods were studied. Combined with the measurementof precision test and measurement of actual data analysis, the author explores the precisiondigital level measurement and operation methods and operation principles.â'‹The thesis puts forward the theodolite reciprocal aiming method to solve the short edgeprecision azimuth transfer and the theodolite intersection point method to solve the forced theplumb point.Difference ranging method in the short distance measurement and effectivelyimprove the precision ranging precision have also been studied.
