Handheld Cell Phone Blocker 16 Bands 5G Jammer

Atomic clock GPS satellite

In the field of timekeeping, clocks are the timekeeping tools that people use on a daily basis, and the accuracy has errors every day and every year. This is enough for people to use GPS jammers daily, but it cannot be satisfied in the fields of production and scientific research that require higher time precision. In order to solve the fields that require high precision, people made atomic clocks, and then successively invented cesium atomic clocks, hydrogen atomic clocks and rubidium atomic clocks according to the principle of atomic clocks.

Cesium atomic clocks use electromagnetic waves radiated by internal electrons jumping between two energy levels as a standard to control the timing of calibrated electronic oscillators and clocks. Cesium atomic clocks are stable by 1 second in 20 million years. Hydrogen atomic clocks use electromagnetic waves radiated by atomic energy level jumps to control and calibrate quartz clocks, whose stability varies by a billionth of a second every day.
