L1B+: A PERFECT SENSOR LOCALIZATION MODEL FOR SIMPLE SATELLITE STEREO RECONSTRUCTION FROM PUSH-FRAME IMAGE STRIPS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
We propose a novel method to generate a single image product from a multi-image strip acquired by a push-frame satellite imaging system. The images of the push-frame strips are combined into a large scale mosaic simulating a perfect sensor geometry.
