Microcomb chips can shrink optical atomic clock and create more accurate GPS systems

Smaller atomic clocks will be used for navigation, autonomous vehicles and geo-data monitoring Optical atomic clocks can increase the precision of time and geographic position a thousandfold in our mobile phones, computers, and GPS systems. However, they are currently too large and complex to be widely used in society. Now, a research team from Purdue […] The post Microcomb chips can shrink optical atomic clock and create more accurate GPS syste…

Chip based microcombs boost gps precision

Berlin, Germany (SPX) Feb 24, 2025 Optical atomic clocks hold the promise of enhancing timekeeping and positioning in everyday devices by a factor of one thousand. Yet their large size and complex design have kept them confined to advanced laboratories. Researchers at Purdue University, USA, and Chalmers University of Technology, Sweden, have now devised a method using on-chip microcombs to dramatically reduce the size of these p
