where ( X, Y, Z ) : ground coordinate of target P ( X(L),Y(L),Z(L) ) : ground coordinate of the position of sensor on scan band L { m it } scan band ( L = MOD( J, 6 ) assumed prinei pa 1 dis tance 1 ) components of rotation matrix on scan band L The position and attitude of sensor are expressed as functions of scan band L since they are ever changing. The concept of scan band is used because LANDSAT MSS scans six lines at a time. It was experimentally found out that the position and the attitude could be expressed by monomials and by trinomials, respectively as below. Angle deviation ( u ) caused by the irregularity of scan mirror rotation is also expressed by a trinomial of pixel number.
