GeoOptics Inc. has upgraded its CICERO constellation of Earth-observation satellites to include advanced GNSS Reflectometry (GNSS-R).

A satellite launching in November will use GNSS – Radio Occultation (GNSS-RO) to collect highly accurate global temperature and humidity information as an aid to more accurate and more advanced weather forecasting. Developed by NASA’s Jet Propulsion Laboratory (JPL), the spacecraft’s GNSS-RO instrument tracks GNSS satellite signals to measure the physical properties of Earth’s atmosphere.

The National Oceanic and Atmospheric Administration (NOAA) will purchase data from small commercial satellites to expand its GNSS radio occultation (RO) efforts to better predict weather.
In September NOAA, through the government’s Commercial Weather Data Pilot program, awarded contracts to San Francisco, California-based Spire Global ($370,000) and GeoOptics ($695,000), of Pasadena, California, to provide RO data. This data will be used to assess whether commercially provided information can be incorporated into the agency’s weather models.
