- Abstract: This is time-series data of the positioning solution of the SGO-A observation point obtained by analysis with GNSS-A analysis software "GARPOS" version 1.0.1 using the GARPOS format GNSS-A seafloor geodetic observation dataset. Data is available in ECEF coordinates and local ENU coordinates. Data published before Feb. 2020 are aligned to the F3 solutions of the Geospatial Information Authority of Japan (ITRF 2005). Data published after Feb. 2020 are aligned to the latest version of the ITRF ITRF2020). Coseismic and postseismic displacements are not corrected. The results may change due to updates in the data analysis method.

- Abstract(J): SGO-A観測点で取得されたGARPOSフォーマットのGNSS-A海底地殻変動観測データセットを用いて,GNSS-A解析ソフトウェア "GARPOS" version 1.0.1による解析で得られる,SGO-A観測点の測位解の時系列データです.地心地球固定座標系と平面直交座標系それぞれのデータがあります.2020年2月以前に公開したデータは,国土地理院のGEONET F3解 (ITRF2005) に準拠した座標系で求めています.2020年2月以降に公開したデータは,ITRF2020に準拠します.本データは,地震時変動や地震後変動の補正はしておりません. なお,データの解析・分析手法は研究開発段階のため,改良によって測位解の値が変化することがあります.
