CICERO (Community Initiative for Cellular Earth Remote Observation) is an array of 24+low-Earth Orbiting (LEO) micro-satellites for performing GPS and Galileo radio occultation (GNSS-RO) of Earth’s atmosphere and surface remote sensing by GNSS reflection.

The system will deliver critical data on the state of the earth to scientists and decision makers worldwide. Products will include high-accuracy profiles of atmospheric pressure, temperature, and moisture; 3D maps of the electron distribution in the ionosphere; and a variety of ocean and ice properties. Principal applications will be weather forecasting, climate research, and space weather monitoring.

CICERO will be built up over time, starting with the launch of a first spacecraft in late 2014. The initial operational constellation (CICERO-I) will consist of six LEOs in multiple orbit planes for broad global coverage. CICERO-I is expected to be operational in at the end of 2016. The constellation will be expanded to 12 satellites in 2017 and to 24 satellites in 2018.

The first one or two satellites are planned to be launched in 2016 with the initial constellation becoming operational in 2017. For later launches, GeoOptics reportedly has an agreement with Virgin Galactic to use the LauncherOne rocket.
