4. Conluding remarks 
The procedure confirmed that if more accurate attitude 
parameters, the fewer ground control points are required. 
The errors of the sensor orientation elements measured 
during the flight are mainly systematic errors and therefore, 
the correction functions have relatively simple form. 
In the proposed procedure either all orientation parameters 
or only those which strongly affect the image geometry should 
be applied. In comparison with other procedures which do not 
use attitude parameters, the number of required control points 
is reduced twice or even three times delivering the same 
level of accuracy.
