Super-wide-area atmosphere and ocean observation technology

IoT satellite earth observation technology

A technology for super-wide-area atmosphere and ocean observation in unexplored regions on a global scale utilizing IoT sensing

Current research

"Super-wide-area atmosphere and ocean observation technology" can directly observe the atmosphere and oceans - at low power consumption and low cost - through IoT sensors installed in all areas of the Earth that have hitherto been difficult to observe directly on a constant and real-time basis.

By developing super-wide-area IoT sensing in cooperation with Low Earth Orbit (LEO) satellites and HAPS, we aim to enable broader, more real-time observations than currently possible, collect data that improves the prediction accuracy of extreme weather and helps solve climate changes, and establish observation technologies that extend into unexplored domains such as the atmosphere and oceans.

As global warming progresses, it has been noted that damage from extreme weather is likely to expand further in the future. To implement appropriate countermeasures based on highly accurate predictions, it is necessary to develop technology that can efficiently and effectively collect and utilize in situ observation data from oceanic areas where data acquisition is currently insufficient.
Therefore, aiming to overcome the limitations of improving the prediction accuracy of weather forecasting that relies on remote sensing by meteorological satellites, our research team is advancing research on new methods.
We are working to collect in situ observation data on extreme weather, such as directly under typhoons, by utilizing "super-wide-area atmosphere and ocean observation technology."
Specifically, with a view to utilizing communication infrastructure, we are engaged in research such as selecting sensors for observation, environmental conditions depending on installation locations, such as on and in the sea, communication speed with satellites, communication methods based on frequency, antenna design, power consumption, and requirements review for satellite IoT sensors.
Starting from fiscal year 2025, we are expanding our observation targets to include linear rainbands and have begun collecting in situ observation data to improve prediction accuracy. We will contribute to building a society that can adapt to increasingly extreme weather phenomena and changes in the global environment by optimizing observation systems through virtual observations and by establishing highly accurate "extreme weather forecasting technology" that utilizes in situ observation data.

Furthermore, through joint experiments and research with national and corporate research institutes and universities and through alliances with manufacturing companies, we will verify the importance of the technology and its use cases in a manner that contributes to the creation of NTT Group's space business.
