A method for the precise and absolute measurement of microwave chirp rates in cold-atom gravimeters

In a cold-atom gravimeter based on Raman transition, the frequency of Raman lasers is controlled by microwave signals. The accuracy of the chirp rates of the microwave signals directly influences the accuracy of gravity measurements. This study presents a methodology for the precise and absolute mea...
