Mitsubishi Electric Unveils Daichi-4 Satellite for Disaster Prevention and Earth Observation
Mitsubishi Electric Corp. unveiled its new Earth observation satellite, Daichi-4, to the media on March 11th. The satellite will utilize advanced radar technology to monitor the Earth's surface for changes that could indicate potential disasters, as well as to assess the impact of disasters after they occur.
"We hope the satellite will contribute to the realization of a safe, secure and comfortable society," said Katsuya Sakai, deputy head of Mitsubishi Electric's Space Systems division.
Daichi-4 is scheduled for launch aboard the H-3 rocket in fiscal year 2024. Developed and manufactured by Mitsubishi Electric over eight years, the satellite weighs approximately 3 tons and spans 20 meters wide with its solar panels and other equipment deployed. The total development cost, including ground facilities, amounts to 32 billion yen ($217 million).
Daichi-4 boasts significant improvements over its predecessor, Daichi-2. It can observe a ground surface four times wider, enabling more frequent observations and the collection of more precise data. This enhanced capability will be crucial for monitoring volcanic activity, ground subsidence, and assessing the extent of damage and flooding following natural disasters.
