Diagram of the GPM Core Observatory Carrying both a dual frequency radar instrument and a passive microwave radiometer, the Core Spacecraft serves as a calibration standard for the other members of the GPM spacecraft constellation. The Core Spacecraft was developed and tested in-house at NASA Goddard Space Flight Center. The GPM Core Observatory orbit inclination of 65 degrees is such that it enables the orbit to cut across the orbits of other microwave radiometers, sample the latitudes where nearly all precipitation occurs, and sample at different times of day. The GPM Core Observatory GMI...
