The compact hyperspectral prism spectrometer for sustainable land imaging: continuing the data record and enabling new discoveries

Ball’s Compact Hyperspectral Prism Spectrometer is being developed for technology insertion in the Sustainable Land Imaging (SLI) program. NASA’s SLI program aims to develop technologies for future Landsat-like measurements. In support of this, NASA’s SLI-Technology program aims to develop a new generation of smaller, more capable, less costly payloads that meet or exceed current Landsat imaging capabilities. By providing continuous visible-to-shortwave hyperspectral data, CHPS will support legacy Landsat data products as well as a much broader range of land science products. We discuss the development of the CHPS technology, initial performance test results, planned airborne demonstration and data distribution to science collaborators, and path to spaceborne demonstration.
