Abstract: The mathematical formal of the ECC is derived.The ECC for various disturbing accelerations which include the vertical acceleration,Eötvös correction,horizontal acceleration correction and free-air correction etc.are analyzed by using the real observations from one airborne gravimetry test.The accuracy requirements for the eccentrical distance and the attitude are also discussed in detail.
