INFLUENCE OF AIR RESISTANCE AND CORIOLIS FORCE ON ABSOLUTE GRAVIMETRY

Zhang Chijun and Zhang Weimin(Institute of Geodesy and Geophysics,CAS, Wuhan 430077)  
The high precision absolute gravimetry has been used in the study of geodesy, geophysics and gendynamics widely. There are many external factors effecting on absolute gravimetry,among which,the air resistance and Coriolis force have scarcely been discussed.The two effects are expound, especially the vacuity desire for FG5 absolute gravimeter that is 1.3332×10-3-1.3332×10-4 Pa has been quoted theoreticly. The proposals how to reduce the influence in gravity observation are presented, as well.
