Recently, the maglev team at the National University of Defense Technology successfully accelerated a ton-class test vehicle to 700 km/h in just two seconds during a maglev experiment. This test speed broke the global record for this type of platform, becoming the fastest superconducting electric maglev test speed in the world.
Precise Positioning: The "Eyes" of the High-Speed Challenge
In this extreme speed experiment, Akusense Sensing, a domestic brand, provided the experimental device with fiber optic sensors with a response speed of up to 16 microseconds, used for real-time monitoring of the precise position of the test vehicle.

Facing the high demands of capturing and feeding back position information in a very short time, this high-precision sensor, with its excellent anti-interference ability and signal transmission stability, ensured the accuracy and reliability of the experimental data.
During the experiment, the test vehicle needed to accelerate from a standstill to 700 km/h in 2 seconds, which placed extremely high demands on the monitoring equipment. Akusense Sensing's fiber optic sensors, with their fast response characteristics, perfectly met this high-speed monitoring requirement, becoming one of the key guarantees for the success of the experiment.
A New Era of Chinese Speed Has Arrived
The maglev team at the National University of Defense Technology has been dedicated to maglev technology since 1980, supporting the successful operation of four maglev lines, including the Beijing Metro Line S1 and the Changsha Maglev Express Line.
On this basis, the team spent 10 years working on key technologies and once again achieved a major breakthrough in the field of superconducting electric levitation propulsion technology. This breakthrough overcame core technical challenges such as ultra-high-speed electromagnetic propulsion, electric levitation guidance, transient high-power energy storage and inversion, and high-field superconducting magnets.
The success of this ultra-high-speed superconducting electric maglev system not only signifies that my country has reached an internationally leading level in ultra-high-speed maglev technology, providing a new option for the future development of vacuum tube maglev transportation in my country, but also provides new methods and means for aerospace propulsion launch and test testing. Its subsequent technological iterations and industrial applications will bring new momentum to the development of my country's aerospace and rail transit industries.
Akusense Sensing is fortunate to be a witness and participant in this major national innovation breakthrough with its independently developed cutting-edge sensing components. In the future, we will continue to dedicate ourselves to the field of precision sensing, providing faster response times, more accurate monitoring, and more stable performance, contributing solid foundational technological capabilities to the independent innovation and accelerated advancement of our country's national defense science and technology.
