Abstract
A method (50) for image acquisition by a spacecraft (10) comprising an observation instrument (20) and a laser transmission module (30), the method includes: acquiring an image of a calibration area referred to as a calibration image, by the observation instrument (S50), obtaining reference data associated with the calibration area (S51), determining a pointing error of a laser line of sight by comparing the calibration image and the reference data (S52), controlling the pointing of the spacecraft by correcting the pointing error, in order to point the laser line of sight towards a laser reception module (S53), and transmitting data to the laser reception module by the laser transmission module (S54).
