Application of Gyroscope Inlong Distance and Large Buried Depth Gas Pipeline Location
For the purpose of inspecting reliability and accuracy of gyroscope's data in long and ultra-deep pipeline measurement and po-sitioning project,this paper takes site excavation verification method into consideration.Site excavation test is conducted at a construction site of trenchless gas pipeline with long and ultra-deep in one city of Guangdong province.After collecting pipeline three-dimensional coordinates with inertial gyroscope at the site,a verification and comparison of site excavation experiment is implemented.It is concluded that accuracy and reliability of inertial gyroscope positioning technology is high enough,meeting requirements in the long distance and deep buried pipeline measurement project.
