<p>Continuous Global Navigation Satellite System observations provide important constraints on crustal deformation and a wide range of geophysical and environmental processes. Here we present a 15-year continuous GNSS dataset for Taiwan, comprising observations from more than 300 continuously operating stations distributed across the island and covering the period from 2010 to 2024. The dataset integrates observations from multiple agencies through a unified and internally consistent workflow that includes metadata handling, precise point positioning processing in the ITRF2020 reference frame, and systematic quality assessment, resulting in daily coordinate time series, station metadata, and associated quality metrics. Three key quality indicators, including data availability, satellite visibility, and the standard deviation of residuals from time-series modeling, are provided to support evaluation of station performance and the reliability of derived products. Instrumental and coseismic offsets are identified and recorded to support consistent and reproducible analyses. The dataset is archived in a version-controlled repository with complete metadata and detailed supporting documentation. This release represents a fixed dataset version to ensure reproducibility. The dataset provides a foundation for investigating crustal deformation, coseismic and postseismic deformation, hydrological loading effects, and other geodynamic processes in Taiwan.</p>
