From page 1...
... of the National Academies of Science, Engineering, and Medicine conduct a short study that would assess the potential use of a proposed multi-user, robot-tended, uncrewed commercial space platform as a potential host for a large number of Earth remote sensing instruments. Specifically, NASA requested that the study: • Consider a notional platform in a Sun-synchronous orbit (SSO, nominally 600–800 km)
From page 2...
... For example, interferometric synthetic aperture radar measurements require a large deployable antenna on a platform with accurate attitude control, accurate pointing, and a highly stable platform. A notional platform flying in a lower orbit could support ice elevation measurements, but only if the platform had the requisite pointing control.
From page 3...
... The committee notes that the greatest potential for the notional platform could be the ability to expedite instrument technology demonstration and incubator projects that may otherwise struggle to find opportunities for deployment in space given relative priorities compared to other parts of the NASA ESD portfolio, such as Earth System Explorers and Earth Venture. Instrument demonstration and incubator projects can often benefit from operation in space with orbits that are not necessarily optimized for science but offer opportunities to retire risk and advance sensor technology and retrieval algorithms.
