Himawari and Mitsubishi Electric Complete Facilities For Weather Satellite Ops
by Staff Writers
Tokyo (SPX) Oct 09, 2013


The ground operations system designed, built and installed by Mitsubishi Electric consists of antennas with a 9-meter diameter and radio frequency and satellite control equipment installed at the main unit in Hiki-gun, Saitama Prefecture, and the sub unit in Ebetsu, Hokkaido.

Himawari Operation Enterprise Corporation (Himawari Operation Enterprise) and Mitsubishi Electric have announced the completion of the ground operations system for the Himawari-8 and Himawari-9 weather data transmission satellites.

The Japan Meteorological Agency (JMA) plans to launch Himawari-8 and -9 in Summer 2014 and 2016, respectively, to enhance public safety and security through relaying sophisticated weather data contributing to disaster prevention and monitoring global environment.

The ground operations system designed, built and installed by Mitsubishi Electric consists of antennas with a 9-meter diameter and radio frequency and satellite control equipment installed at the main unit in Hiki-gun, Saitama Prefecture, and the sub unit in Ebetsu, Hokkaido. Through their involvement in weather satellite operations, the two companies will continue to contribute to disaster prevention and monitoring global environment.

System features
1) Double redundant configuration for stable and accurate operations A two-unit operation scheme ensures stable and consistent observation data transmission to JMA. Each unit features a redundant configuration including antennas with a 9-meter diameter.

2) Timely retrieval of observation data Thanks to the system's alignment to the geographical coverage area of Himawari-8 and -9, observation data can be retrieved once every 2.5 minutes (up to 576 times per day), enabling the provision of up-to-the-minute information on typhoons, rainstorms and other climatic anomalies by geographic sector. Previously, data retrieval was limited to once per day.

3) Cutting back on labor The introduction of an integrated system simultaneously monitoring the two satellites and both ground units enables manpower to be reduced over a 15-year period.

Himawari Operation Enterprise and Mitsubishi Electric will soon begin comprehensive system tests and personnel training for satellite operations for Himawari-8 under the supervision of JMA.

Mitsubishi Electric, which is contracted by JMA to build and deliver Himawari-8 and -9, received the manufacturing order for antennas with a 9-meter diameter, radio frequency equipment and satellite control equipment from Himawari Operation Enterprise in September 2010.

World's Largest Solar Sail, Sunjammer, Completes Test
Tustin CA (SPX) Oct 07, 2013
NASA officials, team partners, and local students were on hand to witness a key milestone for the Sunjammer Mission as it successfully deployed a quadrant of its solar sail - a critical design component that will eventually herald an era of propellantless spacecraft. Sunjammer will be the largest solar sail ever flown using photonic pressure (or sunlight) to maneuver in space. Solar Sails ... read more
