| Outline of Final Research Achievements |
In order to establish real-time and continuous observation technology for seafloor crustal deformation observation by combining GNSS positioning and ocean acoustic ranging, development research was performed to reduce the cost of satellite communications for data transmission and reception. After coding a program for data size reduction, conducting experiments of LoRa communications on land, real-time high-precision GNSS positioning experiments on land, remote islands, and at sea, testing the operation of a series of systems by observing seafloor crustal movement in actual sea areas, and testing long-term data communications via satellite communications, the elemental technologies for the initial purpose were completed. The elemental technologies for the initial purpose have been completed.
