Staggered arrays is the common rule for high resolution earth observing systems, particularly for panchromatic/multispectral acquisition: the linear arrays are shifted in the telescope focal plane along the satellite velocity direction, which means registration performances sensitivity to both terrain elevation and high frequency platform perturbances. This paper aims to show how this sensitivity may be transformed from a drawback to an asset, allowing to retrieve high frequency attitude perturbances ranging above the gyros cutoff frequency or refine the viewing directions, compute digital elevation model and apply superresolution technique with direct applications within the framework of SPOT5, Quickbird and Pleiades-HR satellites.
