ISS attitude control

Dear List,


I am working on a program that superimposes country borders
and city names to the live video provided by the HD cameras onboard the ISS.
The program already works rather well and, a part from a residual distortion at
the corners, the match appears good. 


The problem is that I have to correct the camera angle to
match images taken in different part of the globe, so I am wondering if I am
doing something wrong with the station attitude. Maybe someone of the list can
help me.


I assume that the attitude control of the station uses the
LVLH frame, so I rotate the Z axis of the station toward the Earth’s centre;
the Y axis perpendicular to the orbit plane, and the X axis to complete the


So far, I experienced errors of 5 – 8 degrees, as if the
station was ‘yaw steering’.

the real time overlay:
