위성 영상 획득 자세를 보정하는 방법 및 보정 장치가 개시된다. 본 발명의 일실시예에 따른 위성 영상 획득 자세를 보정하는 방법은, 영상 획득 명령에 연동하여, 지상기반 궤도전파기로부터 위성의 촬영희망 위성위치(P)와 지상계획 촬영시각(T)을 수신하는 단계, 상기 지상계획 촬영시각(T)에 상기 위성이 위치하게 되는 예측 위성위치(P)를 추정하는 단계, 상기 촬영희망 위성위치(P)를 이용하여, 상기 예측 위성위치(P)에서의, 상기 위성에 대한 자세 보정각(dθ)을 연산하는 단계, 및 상기 자세 보정각(dθ)에 따른 상기 위성의 자세 보정 후, 상기 위성에서 영상을 획득하도록 제어하는 단계를 포함할 수 있다.

    A method and a correction device for correcting satellite image acquisition positioning are disclosed. A method for correcting satellite image acquisition positioning, according to one embodiment of the present invention, can comprise the steps of: receiving a desired photographing satellite location (PDesired) of a satellite and a planned terrestrial photographing time (TImaging) from a terrestrial-based orbit propagator in response to an image acquisition command; estimating a predicted satellite location (Predicted) where the satellite is located at the planned terrestrial photographing time (TImaging); calculating a positioning correction angle (dθ) for the satellite at the predicted satellite location (PPredicted) by using the desired photographing satellite location (PDesired); and after correcting the positioning of the satellite according to the positioning correction angle (d9), performing control so as to acquire an image from the satellite.
