Analysis On Precision And Stability Of Gyroscope Total Station Orientation And Application Research On The Relative Technology

Due to the characteristics of the obtainment of gyroscope total station,there Ire few researches on the under-resettlement gyroscope total station.With the thoroughly reliance on the parameter of machine's working stability out of factory for our long-time use in the actual manufactures and engineering,there are a shortage of the latter researches about the checking standards and methods on the comprehensive precision and stability.In the procedure of orientation with gyroscope total station,more and further studies should be put on about the adjustments for details?formula calculations and evaluation of the results.The research contents of the paper are as follows:(1)Set off from the system structure,considering the very non-ignorable influence on the high-precision orientation referring to the eccentricity vector,I put forward the Orthogonal-observation method for vector detection,at the same time I established a compensation model for the orientation value.The achievements offer a reference for the latter use and result corrections.(2)Referring to common gyroscope total station,considering the temperature gap between up and under-ground,I completed the temperature's influence detection based on the variance and regression analysis.It evaluates the accuracy of the compensational formula for the gyroscopes with poor adaptation in various temperatures.Based on the Instrument parameters and the adjustment of times for measurement,the further achievement is the unbiased and the accurate values.(3)Starting with from anharmonic vibration,combining with the research on the actual working station and the parameters of gyroscope,I established the stability scale of gyroscope total station;According to the analysis of working station of gyroscope in various environmental implication,it demonstated the change of fuzzy stability in the actual project.Referring to the actual inner and outer precision of gyroscope,this paper established a high-prcision control-network of GPS based with the detection of measuring robot,aiming at the stability and precision analysis of gyroscope total station in the actual engineering application.(4)Continuing from the research on meridian convergence angle need in gyroscope orientation,I got the analysis of the attention matters in calculation with simple formula.According to the rule of the change for meridian convergence angle,combining with the relative distance and bearing between the up and underground edges,I conclude the simple method to achieve the value of meridian convergence angle referring to the about relative distance and bearing.Then I analyzed the possibility and attention on the matually use of meridian convergence angle for different coordinate systems.At last,I got another research on the contrast and transformation for meridian convergence angle from various coordinate systems.Then I wrote simple software for the formula of meridian convergence angle to get a efficiency improvement.At last,taking Xuzhou city for example,this paper arose the Conversion and using matters for the meridian convergence angle between the coordinate system 1954 and 1980.
