Common Instrument Interface

The Common Instrument Interface (CII) Study Activity supports Earth Science Directorate (ESD) by identifying a common set of Earth Science instrument-to-spacecraft interface guidelines that will improve the likelihood that these instruments become hosted payloads on hosted payload opportunities. CII works with industry, academia, and other government agencies to analyze the interface trade space, which helps ESD understand the key drivers in the matching process. CII also hosts periodic workshops to bring together stakeholders to review team guidelines and nurture relationships within the community.
