Over the last twenty years,the novel inertial sensors based on atom interferometer have a rapid development,such as atomic gravimeter,atomic gyroscope,and atomic gravity gradiometer.They have attracted worldwide attentions due to their remarkable stability,high sensitivity,high repetition rate and potentially high accuracy.They could be widely used in the field of the fundamental physics and applied science.The previous atom gravimeters could only operate in the laboratories due to their bulk volume.Lots of efforts have been made to simplify the laboratory-based experimental apparatus so as to build compact and transportable atom gravimeter.Such mobile devices are of great usage for a wide range,such as geophysics,resource exploration,seismic studies,gravimeter survey,inertial navigation and so on.Recently,the mobile atom gravimeter has become a reality as the rapid development of the new technologies; and the performances could be comparable with the best classical gravimeter.In the future,they may be installed in the mobile platforms,such as the plane,truck,warship,and even satellite.Recently,we have designed and realized a high precision atom gravimeter.Currently,with the interrogation time 2T = 120 ms and the repetition rate 2.2 Hz,a sensitivity of 1.1x10-8 g@200s has been reached in our experiment.The tidal phenomenon is observed by monitoring the local gravity continuously over 128 h based on our atom gravimeter.Moreover,a whole seismic wave occurred in Pakistan was recorded in detail with our atom gravimeter and the results are very consistent with that recorded by a traditional seismic detector.Finally,the absolute gravity value at the location of our laboratory has been measured,the uncertainty of the measurement is about 1x10-7 g.The current performance of our gravimeter meets the most of the field applications.
