More Information
Summary: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.
