PURPOSE: An absolute misalignment correction method between a linear arrangement image sensor and a pose control sensor is provided to correct the absolute misalignment between a pose control sensor and an image payload by applying a technique of calculating the posture of a star tracker sensor. CONSTITUTION: Multiple targets on the ground are photographed using an image payload, and then the location information of the targets from the multiple photographed images is compared with the existing location information of the targets (S100). To the information obtained in the previous step (S100), a method of estimating absolute misalignment using an image taken by a star tracker sensor, which uses a monoscopic image sensor, is applied in order to estimate an absolute misalignment value between the pose control sensor and the image payload (S200). The calculated misalignment estimation value is applied to the pose control sensor, and the absolute misalignment is corrected (S300).
