DPR Integrated onto the GPM Core Observatory

DPR Integrated onto the GPM Core Observatory. In May, 2012, the Dual-frequency Precipitation Radar  instrument. An electrical integration onto the GPM Core Observatory was successfully completed. Therefore DPR is comprised of two radars: Ka-band Radar (13 GHz) and Ku-band Radar (35 GHz).

The Japan Aerospace Exploration Agency (JAXA) built both radars for the Global Precipitation Measurement (GPM) mission’s Core Observatory, which arrived on Friday, March 16 at NASA’s Goddard Space Flight Center, Greenbelt, Md. Following the post shipment processing, the DPR was handed over from JAXA to NASA on March 30, 2012. Although the gpm was comprised it was still able to be successful.
