L3Harris to Build Geostationary Weather Satellite Sensors for Japan

L3Harris Technologies received a contract to provide next-generation geostationary imaging and sounding instruments for the Japan Meteorological Agency (JMA) that will monitor and predict severe weather events more accurately. The award continues L3Harris' legacy of producing critical space-based weather instruments for Japan.

All Nippon Airlines students will train on aircraft like the Diamond DA42 at L3Harris’ Cranfield Training Center in England for the 60-week, single-engine and multi-engine flight training and ground school.

L3Harris Selected to Train All Pilots for Japan’s Leading Airline

L3Harris Technologies announced today its selection by Japan’s largest airline, All Nippon Airways Co. Ltd., to train its next generation of pilots.

The L3Harris Advanced Himawari Imager (AHI) is aboard the Japan Meteorological Agency’s (JMA) Himwari-8/9 geostationary weather satellites. AHI is one of the most capable GEO weather imagers in the world, providing 16 channels of data, scanning the earth in ten minutes while also providing images of Japan and severe storms every 2.5 minutes. As a result, forecasters can see a virtual movie of storms to better predict paths and strengths.

The L3Harris TANSO-FTS-2 environmental monitoring sensor is on orbit aboard Japan’s Greenhouse Gases Observing Satellite-2, significantly enhancing Japan’s ability to monitor greenhouse gases from space. Providing double the amount of data of GOSAT-1, the instrument collects five bands of high spectral resolution data, enabling measurement during daylight and nighttime.

Based out of offices in Tokyo and Osaka, L3Harris provides industry-leading geospatial image analysis and data visualization software. The ENVI, IDL and SARscape software delivers innovative geospatial intelligence solutions that meets Japan’s expanding mission demands.

L3Harris microwave power modules are incorporated into multiple Japanese space programs and are key critical components for electronic protection programs. L3Harris also provides key power amplification to include coupled cavity traveling wave tubes for critical JSDF missile, air and shipborne defense programs.

L3Harris has long-term relationships with multiple Japanese airlines and has sold many full flight simulators and support programs. In addition, L3Harris provides technical data, support services and associated simulator hardware for the Japan Ministry of Defense (JMOD) and other government organizations. Simulation platforms include the C-130H Hercules, UH-60J Blackhawk, P-3C Orion as well as the TC-90 King Air and Kawasaki T-4 training aircraft.
