.y/jtg-1 Gyro Station Performance Study

The gyrotheodolite is a kind of defining orientation physical instrument can measure true northern within the scope of degree of latitude 70 ° . Because it have the ability to navigates independent in all-weather and not depend on other conditions , Since appear, it cause the people to pay much attention and was always been broadly make use of in the realms, such as voyage aviation aerospace and military...Etc. and have been one of the techniques of all countries to develop important. With the quick development of science technique economy and national defense, the technical request of the gyrotheodolite become more and more high, want to satisfy the need of the fast and high accuracy to definite orientation particularly. But still didn't have domestic and high accuracy gyrotheodolite model.This text emphasized to elaborate the design principle and control to constitute of the high accuracy and half automatic gyro total station instrument of Y/ JTG-1 be equip by the top instrument and the total station instruments of TDA5005; in the foundation of analyzing the definite direction accuracy and its error margin factor, combine the function characteristics of the instrument, examine the function index sign of the instrument; Reform the definite orientation method used for up the pose gyrotheodolite, put forward the principle and the method of converse point to definite orientation at under the pose gyrotheodolite.But, without a set of integrity norm to check of the high accuracy top whole station instrument in domestic.The text put forward main contents to check the top theodolite with high accuracy at the foundation of examine the whole stations top instrument of Y/JTG-1, put forward the homologous examination method and index for the request to various contentses, and carried on the study to check the Tightness of the examination device and designs.
