China Has Broken The Us And European Blockades To Capture A Technology That Could Help Drones Pinpoint Their Location

Feb 13, 2019

China has made continuous progress in cutting-edge science and technology, including the j-20 stealth fighter, aircraft carrier and chang 'e-4. For ordinary Chinese who go to work and get off work every day, the progress of national science and technology, very happy and very proud, but feel that these cutting-edge technology is far away from their own.

A recent technological breakthrough seems to have made a difference. At the end of December 2018, sinopec announced that the detection technology of large-caliber submarine long-haul crude oil pipeline was conquered, which had been monopolized by European and American countries before, and China once again broke the technological monopoly of Europe and America.
The technology, which can be easily understood literally, is to monitor large-bore pipelines under the sea. Oil is directly related to our life, and the safety of the oil pipeline concerns everyone's life.
The detection of the hangzhou bay submarine crude oil pipeline is more than 53 kilometers long and the pipeline diameter is 762mm. The detection of the large-diameter submarine crude oil pipeline requires three technologies, one is the three-axis high-definition magnetic flux leakage detector, the other is the inertial navigation measurement system, and the third is the pipeline stress detection system with weak magnetic technology.

Three-axis high-definition magnetic flux leakage detection technology has been conquered in China several years ago. In 2014, the three-axis high-definition magnetic flux leakage detector with a diameter of 1219mm was successfully applied to the detection of the west-east gas pipeline.
This time, the focus is on the inertial navigation measurement system, which is originally a military technology. This technology is composed of inertial measurement device, computer and control display, and combines the earth rotation and gravity acceleration to calculate the position data of fighter, military aircraft and uav.
In the detection of the submarine crude oil pipeline, this technology not only maps the pipeline center line information and determines the pipeline displacement, but also can locate the data of the longitude and latitude of the defect and accurately locate the problem.
Inertial navigation, a technology that has been used for civilian applications and has broken the west's technological blockade of the field, is not so simple.
The excessive dependence of modern information warfare on satellites has become one of the anxieties of great powers. Anti-satellite weapons, ranging from lasers and missiles to space satellite hunters, are making continuous progress. Once a war starts, satellites are highly likely to be the first to be attacked.
