The Beidou navigation system’s technology has been improving continuously with its applications expanding greatly, thus leading to the use of its high accuracy positioning services across various fields such as military precision guidance and civil sectors like transport, agriculture, fishing industry, meteorology among others that have demonstrated great interest in drones and smart logistics. Just lately, during installation of the much-anticipated Shenzhen-Zhongshan Channel submarine tunnel immersed tube, the Beidou Navigation System proved itself again by helping to achieve millimeter-level docking accuracy with its superior positioning accuracy.
Shenzhen-Zhongshan Channel is an important transportation project that links Shenzhen with Zhongshan and has very stringent requirements for the accuracy of submarine tunnel immersed tube installation. In response to these conditions, Beidou navigation system which can make high precision positioning has become a necessary helper. During the process of installation, satellite positioning signals are received by Beidou navigation system’s main antenna dish and handed over to smart construction thus correctly assisting submerged tube alignment on sea bottom.
Due to its submarine laying through the Shenzhen-Zhongshan Channel, the installation of which has extremely strict requirements on precision, it is necessary that each pipeline section should be accurately placed at once. In this regard, Beidou system’s positioning accuracy reaches millimeter level, thus solidifying its contribution to the work of installation. It is reported that due to Beidou system assistance, Shenzhen-Zhongshan Channel achieved mm-level docking accuracy. Half of immersion tubes reached mm-level docking and realized 7 consecutive dockings with a 1mm tolerance for the “Shenzhong Accuracy”. This surpasses the five centimeters error specified by design.
The successful application of Shenzhen-Zhongshan Channel not only verifies once again the fine positioning ability of Beidou navigation system but also shows its vast prospects in ocean engineering field. As Beidou navigation technology continues advancing and its applications broaden, it will remain relevant in future as it would be instrumental in ensuring accurate constructions and effective management in many other fields as well.
At the same time, this also indicates that the Beidou navigation antenna market will continue to maintain a strong development momentum in the next few years. With the increasing application demand in more fields, the market demand for Beidou navigation antennas will also continue to grow. In the future, we have reason to believe that the Beidou navigation system will show its unique advantages and value in more fields and make greater contributions to promoting my country's scientific and technological progress and economic and social development.
