Analysis on frequency spectrum of residual error from A-10 absolute gravity meter

ZHAO Luo-cheng①,LUO Zhi-cai①,WANG Dong-xiao②,WANG De-zheng②(①School of Geodesy and Geomatics,Wuhan University,Wuhan 430079,China;②Surveying and Mapping Institute of Sanya City,Sanya 572003,China)  
There are obvious periodic signals in residual errors from measurements of free fall absolute gravity meter A-10,the residual errors from 4 stations are processed with FFT,frequency spectrum are analyzed,the results indicate frequency spectrum of set average of residual error are more stable,the main peak frequency is independent of station,the main peak amplitude is dependent of station,the absolute gravity values are lower after periodic corrections.
