Sending occultation data to the ground for timely assimilation into weather forecasts and other near real-time monitoring needs is a critical CICERO requirement. Latencies of less than an hour are desired for weather forecasts, less than five minutes for space weather hazard monitoring. Achieving this with direct-to-ground links from a distributed constellation requires an extensive ground network. An alternative is to downlink through geosynchronous relay satellites, though this would require additional up-front development. Both approaches are under evaluation for CICERO.  (The Inmarsat-4 relay satellite is shown above.)
