The Satellite Applications Mission Directorate I develops satellites for Earth observation, communications, and positioning. In so doing, we help ensure a safe and secure society.
New arrival information from The Satellite Applications Mission Directorate I,JAXA.
Dual-frequency Precipitation Radar (DPR) will be installed on the core satellite of the Global Precipitation Measurement (GPM) mission. This was announced to the press at the Tsukuba Space Center on February 9.
At the press conference speakers from JAXA, National Institute of Information and Communications Technology (NICT) and National Aeronautics and Space Administration (NASA) gave an outline of DPR and the main GPM satellite, and explained how GPM mission and DPR will contribute to the hydro meteorological disaster mitigation, such as the prediction of flooding and improvement in the accuracy of numerical weather prediction and typhoon forecasting, as well as in research fields such as the elucidation of climate and water cycle variation.

JAXA developed the DPR to be installed on the GPM sore satellite in cooperation with NICT. The obtained data by DPR that will be the world leading of the instruments for precipitation measurement will be used as a calibration standard for rainfall estimation from the GPM constellation satellites.
GPM mission will enable global measurement of precipitation every three hours. The GPM core satellite will be launched atop the H-IIA launch vehicle in FY2013.
