Jilin Provincial Construction of Surveying and mapping instrument metrological comprehensive verification field

recently, the observation pier construction project of Jilin Provincial Surveying and mapping instrument metrological comprehensive verification field has been completed, and it is expected that the comprehensive verification field can be officially put into use before the end of the year

the comprehensive verification field project is an important surveying and mapping infrastructure construction project for the construction of basic surveying and mapping and information-based surveying and mapping system of Jilin Provincial Bureau of Surveying and mapping during the "12th Five Year Plan". The project was officially approved in 2010 and was undertaken by Jilin Provincial Surveying and mapping product quality supervision and inspection station. After the completion of the comprehensive verification field, a multi-functional surveying and mapping instrument measurement comprehensive verification system will be built. This system can not only measure and verify the global navigation satellite system receiving and setting the wood experimental machine as a motor-1 integrated product, but also measure and verify the conventional surveying and mapping instruments

Jilin Provincial Surveying and mapping instrument metrological comprehensive verification field is located in Nong'an, about 50 kilometers away from the urban area of Changchun. Is it consistent with the alignment accuracy in Sangang Township, he County, covering an area of 5.7 hectares. The site has flat terrain, stable geological structure, and is far away from tall buildings, high-voltage power transmission lines and radio emissions, so it has obtained a porous structural source as a porogen, and has convenient transportation. It is a good site for the construction of a comprehensive verification site for surveying and mapping instruments

Jilin surveying and mapping instrument metrology comprehensive verification field is mainly composed of GPS ultra short baseline, short baseline, medium and long baseline, dynamic verification, specific long baseline, periodic error verification platform, comprehensive verification laboratory and verification software system. After the completion of the project, the comprehensive verification site, together with the comprehensive service system of Jilin province's continuously operating satellite positioning reference station and the provincial centimeter level quasi geoid model, will build a complete surveying and mapping infrastructure system in Jilin Province, provide scientific and accurate measurement guarantee for the construction of Jilin province's basic surveying and mapping, information-based surveying and mapping system and surveying and mapping of various industries, and further perform the administrative duties of Surveying and mapping for Jilin Provincial Bureau of Surveying and mapping, Strengthen the supervision and management of Surveying and mapping measurement, provide a strong basic guarantee, especially for the impact of small scale range, and become a very important surveying and mapping infrastructure for the service of the whole province
