Monitoring the Earth's deformation with the SPOTGINS series
Abstract. A distributed Global Navigation Satellite System analysis center, designated SPOTGINS, has been established by several research groups that utilize the GINS software and the CNES-CLS precise products. Despite the heterogeneity in their research objectives, the SPOTGINS members apply the same configuration and metadata. The computed global ambiguity-fixed precise point positioning time series are fully consistent among the members, and are subsequently published as a single product (https://doi.org/10.24400/170160/20250414, Santamaría-Gómez et al., 2025). At the time of writing (August 2025), the SPOTGINS dataset includes 5768 daily series from May 2000 to present. This product facilitates a range of research activities, including but not limited to the precise monitoring of the Earth's deformation. A comparison of the SPOTGINS series with published series from the Nevada Geodetic Laboratory solution shows no significant difference in quality.
