Jitter compensation system in solar X-EUV imaging telescope

  • The constant attitude control motions of the satellite often result in a platform that is not stable enough for mounting a high-resolution telescope. The jitter compensation system commands the CCD camera to shift one phase in the appropriate direction so that light from a point of the sun will continue to fall into the same CCD potential well. The CCD pixels phase shift along the detector-s columns which are aligned parallel to east-west. The high accuracy sun sensor (HASS) uses two reticles, which one is for each axis to determine the relative position of the sun. Only one axis of the HASS data is used for motion compensation. The north-south pointing errors are significantly smaller then the east-west errors, and are not compensated for by the system. The jitter compensation system incorporates HASS that is used in a semi-closed loop system to shift the CCD potential wells in order to compensate for jitter in one dimension. The motion compensation system can remove the solar "drift" and the solar array jitter during the exposure, and the X-ray imaging performance will be improved.
