Advanced technology land imaging spectroradiometer: a next generation sustainable land imager

The Advanced Technology Land Imaging Spectroradiometer (ATLIS) is a small (0.04 m3), multispectral pushbroom imager to provide visible through shortwave (VSWIR) calibrated imagery for the Sustainable Land Imaging-Technology (SLI-T) reference mission architecture (RMA) [1]. ATLIS is designed to provide imaging spectroradiometry that meets SLI-T RMA key parameters with an instrument that is much smaller and much less massive than previous land imaging systems. This paper describes a NASA ESTO funded project to design, build and test a six spectral band prototype ATLIS called ATLIS-P that will establish whether this compact, low mass design approach with wide field of view (WFOV), free form reflective telescope, large format, small detector digital FPA and on-chip processing meets SLI-T RMA VSWIR requirements.
