According to estimates by the Cabinet Office, the domestic market for the space industry is expected to reach approximately 4 trillion yen in 2024. The World Economic Forum also predicts that the international market for space business will reach approximately 260 trillion yen in 2035, about three times the current market size. The space industry can be divided into two main categories. The first is the space equipment industry, which manufactures satellites and launch vehicles, and the second is the space applications industry, which uses satellites to transmit and receive data. The main areas of the space application industry include telecommunications broadcasting, positioning and remote sensing, with consumer-oriented services accounting for by far the largest proportion. As a result, attention is focusing on the creation of new related markets using technologies such as big data and artificial intelligence.
This paper focuses on remote sensing technology, which has been utilized along with the recent development of space technology, with the aim of understanding its measurement principles and introducing examples of domestic and international technology utilization and research and development, mainly in the area of terrestrial remote sensing.
