+The [Space-based multi-band astronomical Variable Objects Monitor (SVOM)](https://www.svom.eu/en/the-svom-mission/) is a French-Chinese mission, result of a collaboration between the two national space agencies, [China National Space Administration (CNSA)](https://www.cnsa.gov.cn/english/index.html) and [Centre national d'études spatiales (CNES)](https://irfu.cea.fr/dap/en/Phocea/Vie_des_labos/Ast/ast_technique.php?id_ast=2276). SVOM mission is dedicated to the study of the the most powerful transient phenomena, with a particular emphasis on gamma-ray bursts (GRBs).
+
+The SVOM spacecraft carries four multi-wavelength instruments: ECLAIRs, Gamma Ray burst Monitor (GRM), Microchannel X-ray Telescope (MXT) and Visual Telescope (VT). ECLAIRs and GRM can detect gamma-ray transient sources in real-time with localisation capabilities for ECLAIRs. SVOM can transfer the alerts in near real-time with a typical latency of less than 30s for 2/3 of the alerts and perform autonomous slew for performing x-ray and optical follow-up of the source with the smaller field of view of theMXT and VT instrument

+#### JSON-Serialized GCN Notice Types in GCN Kafka
+
+SVOM distributes alerts and localizations detections of gamma-ray transients. These notices are published on the GCN Kafka and VOEvent topics as `gcn.notices.svom` and `gcn.notices.svom.voevent`, respectively.
