Linear Pushbroom Cameras

Modelling and analyzing pushbroom sensors commonly used in satellite imagery is difficult and computationally intensive due to the motion of the orbiting satellite with respect to the rotating earth, and the non-linearity of the mathematical model involving orbital dynamics. The linear pushbroom model) introduced in this paper has the advantage of computational simplicity while at the same time giving very accurate results compared with the full orbiting pushbroom model. The common photogrammetric problems may be solved easily for the linear pushbroom model.
