Abstract

Currently, the Geospatial Information Authority of Japan routinely operates the GNSS analysis system to produce coordinate solutions using a GNSS station network called GEONET. The sampling rate of these coordinate solutions is 1 day, or 3 hours at the highest. To augment the system to produce coordinate solutions with higher temporal resolution, a GNSS analysis system to produce kinematic coordinate solutions using the GEONET stations has been developed. This analysis system adopts the precise point positioning strategy to make the system robust and lightweight. In fact, the system is so lightweight that it can be operated with two personal computers. The system produces three types of coordinate solutions with intervals of 30 s, depending on their latency. Each coordinate solution has a quality represented by a typical coordinate repeatability of 1 cm in horizontal components. The system has been successfully utilized in constructing a fault model of the 2016 Central Tottori Earthquake. In the future, the system will be updated to host capacities for 1) producing post-processing 1 s coordinate solutions and 2) producing real-time 1 s coordinate solutions.
