Center of mass correction of ADEOS-II is given as follows:

Position vector from center of mass ( COM ) to LRRA is

where

: Position vector of LRRA optical origin from figure origin in body fixed coordinate

: Position vector of COM from figure origin in body fixed coordinate

: Position vector of LRRA optical origin from COM in body fixed coordinate

Transformation from body fixed coordinate to inertial coordinate is performed as follows:

: Position vector of LRRA optical origin from COM in coordinate

: Rotation matrix from body fixed coordinate to inertial coordinate

Calculate position vector of COM and LRRA from station in inertial coordinate

　　

: Position vector of COM from geocenter in inertial coordinate

: Position vector of station from geocenter in inertial coordinate

: Position vector of COM from station in inertial coordinate

: Position vector of LRRA from station in inertial coordinate

And COM correction value R is given as:
