Title:
METHOD AND CORRECTION DEVICE FOR CORRECTING SATELLITE IMAGE ACQUISITION POSITIONING
Document Type and Number:
WIPO Patent Application WO/2020/096145
Kind Code:
A1
Abstract:
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 (P Desired) of a satellite and a planned terrestrial photographing time (T Imaging) from a terrestrial-based orbit propagator in response to an image acquisition command; estimating a predicted satellite location (P Predicted where the satellite is located at the planned terrestrial photographing time (T Imaging); calculating a positioning correction angle (dθ) for the satellite at the predicted satellite location (P Predicted) by using the desired photographing satellite location (P Desired); and after correcting the positioning of the satellite according to the positioning correction angle (dθ), performing control so as to acquire an image from the satellite.
