[SCG70-11] Current Status and Recent Development of REGARD, GNSS real-time analysis system
Keywords:GNSS, REGARD, MADOCA
REGARD is useful for monitoring crustal deformation as well as estimating fault model. Although the accuracy of RTK results was less than that of post-processing analysis and depended on the baseline length which sometimes exceeds 1000 km, REGARD detected crustal deformation in real time when the large earthquake occurred. On the other hand, the system sometimes could not detect crustal deformation because of the small displacement. In order to operate the system more stable, analysis and inversion method should be improved. Therefore we try to make original ephemeris to use QZSS because IGS real time ephemeris used for RTK analysis are estimated only GPS and GLONASS. We experimentally produced GNSS ephemeris including QZSS by using MADOCA (Multi-GNSS Advanced Demonstration Orbit and Clock Analysis) and investigated their accuracy.
In this presentation, we introduce recent event detected by REGARD and its development, results of MADOCA products.
