The new watch has smaller dimensions but offers better performance than the previous ones

 

The future of time calculation speaks Chinese. The ultra-thin Chinese rubidium atomic clock, which is only 17 millimeters thick, was put into mass production. The watch, developed in 2018 by a research institute of China Aerospace Science and Industry Corporation Limited, is the key to the positioning and timing accuracy of BeiDou navigation satellites.

Compared to the previous generation, the new watch has smaller dimensions but offers better performance, adopting a plug-in design, which simplifies the insertion and removal on the circuit. With greater resistance to high temperatures, it can operate at 70 degrees Celsius.

 

The ultra-precise watch will have a broader market perspective in the future

 

The watch can be used in areas such as aeronautics, aerospace and telecommunications. According to its developers, the ultra-precise watch will have a broader market perspective in the future.

A large number of self-developed rubidium and hydrogen atomic clocks have been carried by satellites that provide accurate positioning for the Chinese satellite navigation system BeiDou. Atomic clocks, moreover, are work horses that send synchronized signals so that satellite navigation receivers can triangulate their position on Earth.
