Beidou satellite navigation system is a magnificent project independently developed by our country in order to get rid of the limitation of other countries' positioning systems. After decades of exploration, discovery and construction. In the end, our country will realize the idea of independent orientation without relying on others. And we all know that the Beidou satellite navigation system is widely used today.
According to the recent understanding, engineers of China Railway Fifth Survey and Design Institute Group Co., Ltd. and Wuhan University used a Taipei bucket inertial integrated navigation railway track geometric state measuring instrument at the construction site from Chaoyang Hub to Shunyi Section of Beijing-Shenyang high-speed railway. The staff commonly called it? Beidou inertial navigation car? . The car is located and works through Beidou navigation system, and can move at the speed of three to five kilometers per hour on the newly laid track, and carry out multi-round precision measurement tasks on the road section.
it is understood that this time? Beidou inertial navigation car? The successful application of Beidou-3 is the first engineering application in the field of high-speed rail construction after the launch of Beidou-3, which is of great significance to strengthen the connection between Beidou navigation system and high-speed rail construction in the future. According to the relevant person in charge, this car not only supports the Beidou-3 satellite navigation receiver but also supports the inertial navigation system. It can replace the traditional track precise measurement method, quickly obtain the three-dimensional coordinates, attitude and track gauge of the track, and realize the efficient measurement of some complex parameters.
after the staff? Beidou inertial navigation car? Compared with the data of working parameters for more than ten days, it is found that the accuracy of the geometric parameters inside the track has reached millimeter level, and the mileage has reached centimeter level. Moreover, the Beidou satellite navigation system has a more reliable performance advantage in the face of complex scenes, and can be improved by more than 2 times than the previous measurement methods. With the addition of Beidou satellite navigation system to our production and even life, I believe that our life will undergo some qualitative changes. This also provides an important guarantee for the location information security of our country.
