Research on rapid surveying and mapping of outfield absolute gravity based on vehicle-mounted atomic gravimeter

The information about Earth’s gravity field is an important basic necessarily for geodesy, geophysics, geodynamics and other disciplines. mapping of effective mean to obtain the information. Compared with surveying based on satellite, ship, airplane, vehicle-mounted has advantages strong flexibility, high spatial resolution accuracy. A short baseline or a small-scale can be realized combination relative gravimeters high-precision absolute reference point. However, this method not suitable situation long large-scale due drift gravimeter. In work, system rapid built up miniaturized atomic inner precision instrument evaluated 0.123 mGal, outer 0.112 mGal in test which contains 12 points 3 km distance. Furthermore, system, data are obatined within 2 min adjusting 5 measuring downtown each measured 19 carried out route covers 24 km. 0.162 0.169 mGal. Finally, free-air anomalies obtained from gravimeter fitting results satellite model analyzed, it found that trends changing basically consistent other. This paper provides new proposal field.
