The Chinese Ground Follow-up Telescope is an optical facility upgraded to support the Space Variable Objects Monitor (SVOM) mission. Located at the Jilin Observation Station, it is capable of rapidly identifying and monitoring the optical counterparts of gamma-ray bursts. The 1.2 m telescope is equipped with two switchable focal-plane instruments: the prime-focus Large-FOV Transient Imager with CMOS and the Cassegrain-focus Camera with Three Channels. In this paper, we present a system overview, including the observatory, the telescope, the instrumentation, the automated operational framework managed by the Operation Center, and the data processing pipelines. We also report the performance results obtained over one year of SVOM’s post-launch operations. The results demonstrate that the system meets its design specifications and delivers robust observational and operational performance.
