Himawari 9 ( Japanese ひ ま わ り 9 号 , Himawari 9-gō , Eng. "Sunflower 9", GMS 9) is a weather satellite of the Japanese meteorological agency JMA ( Japan Meteorological Agency ). It is the ninth geostationary weather satellite in Japan and the second in a new series.

Himawari 9 was launched into orbit on November 2, 2016 at 06:20 UTC by an H-2A launcher from Ramp 1 of the Yoshinobu launch complex at Tanegashima Space Center, Japan . It is planned that Himawari 9 will initially serve as a reserve satellite and later take over the regular weather monitoring of Himawari 8 . The satellites should be positioned very close to each other at 140 ° East, so that there are almost no changes in the viewing angle when switching between the satellites.

construction

The satellite was built on the basis of the DS 2000 satellite bus from Mitsubishi Electric and has a planned service life of 8 years. It is equipped with three sets of devices. The Advanced Himawari Imager (AHI) is the main instrument of the spacecraft. This was built by ITT Exelis - now part of Harris Corporation - in the United States of America and is based on the Advanced Baseline Imager (ABI) of the US geostationary weather satellite GOES R of the US weather agency NOAA. It is a multispectral camera with sixteen channels (0.46–13.3 µm) that will provide overview and detailed images in the visible light and infrared range . The images achieve a resolution of up to 500 meters and provide data on cloud cover, temperature, wind, precipitation and aerosol distribution in the various spectral ranges . The Space Environment Data Acquisition Monitor (SEDA) collects data about protons and electrons in space. The Data Collection Subsystem (DCS) is the communication payload and is used to collect and forward the data to the ground weather stations via the Ka-band . The energy supply is provided by two solar cell booms built by Mitsubishi Electric Corporation, which deliver up to 2.6 kW.
