WebApr 1, 2000 · Without atomic clocks, GPS navigation would be impossible, the Internet would not synchronize, and the position of the planets would not be known with enough accuracy for space probes and landers to be launched and monitored. Atomic clocks are not radioactive. They do not rely on atomic decay. WebSo each GPS satellite has an atomic clock, the most stable and accurate time reference ever developed (using the element Rubidium most of the time), and it uses that clock to broadcast its time.
