The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. Begun in the late 1960s, the acquisition of moderate-resolution, multi-spectral imagery was a revolutionary concept. Subsequently, over its nearly five-decade history, Landsat data has achieved international usage across a diverse set of public/private sectors, including geologic mapping and exploration, precision farming, forestry, climate change, environmental monitoring, droughts, floods, earthquakes, tsunamis, infrastructure, urban planning, social media, water resources, and even the discovery of new species.
SaraniaSat Inc. is proposing a public/private partnership to NASA’s Sustainable Land Imaging (SLI) program for a “paradigm-shift” leading to the next revolution, namely the transition of the Landsat program from a single or dual satellite configuration to a 15 small-Landsat constellation or “Landcon” program incorporating several, exciting technological advances with an emphasis on generating global timely and actionable information for a broad range of sectors. To be actionable, our proposed “H3” paradigm-shift will involve hyper-spatial (10m), hyper-temporal (daily revisit), and hyper-spectral (402 narrow wavebands) resolution imagery. Generation of H3 imagery will result in a revolutionary and fundamental paradigm-shift in earth-observation, remote-sensing science principles from acquiring individual, spectral data points of current generation of satellites to acquiring complete spectral “signatures” of every phenomena being observed on the Earth.
