Accuracy Analysis of Static State Angle Measurement of Theodolite

Modern photoelectronic theodolite has many advantages,such as real-time measurment,high accuracy,auto-tracking monitoring and easy image reconstruction.It is widely applied in scientific and military area covering of aviation,aerospace,and weapon test.Its measuring accuracy has strong effect on the measuring result and test flying conclusion,and the angle measurrement accuracy is the most important in the photoelectronic theodolite.According to working status of the photoelectronic theodolite,its measuring error can be divided into static state error and dynamic state error.Generally,the static state error in the total error of the equipment is the main part,so it is the key that is being studied.The paper aims at theodolite indoor measuring accuracy analysis,the factors that influence the measuring accuracy,and also gives a revised table of the theodolite static state measuring error.
