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

<div className="overflow-table">

| Instruments | Energy Range | Field of View | Localization |
| ----------- | ------------------------------------------------------ | ------------- | ---------------------------------------------- |
| ECLAIRs | 4 - 250 keV | 2 ster | ~8ʹ radius (statistical, 90% confidence) |
| GRM | 15 - 5000 keV | 2.6 ster | ~1-10° radius (statistical, 90% confidence) |
| MXT | 0.2 - 10 keV | 1.1° x 1.1° | ~10-100ʺ radius (statistical, 90% confidence) |
| VT | 450 - 650 nm (Blue band) <br/>650 - 1000 nm (Red band) | 26ʹ x 26' | ~1ʺ radius (statistical, 90% confidence) |

#### 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.

<div className="overflow-table">

| Type | Contents | Latency |
| ------------------ | ----------------------------------------------------------------------------------------- | --------- |
| `trigger` | eclairs.trigger.wakeup, eclairs.trigger.not-slewing, eclairs.trigger.slewing, grm.trigger | ~1-10 sec |
| `mxt.localisation` | mxt.localisation | ~1 min |
| `refined` | eclairs.refined, grm.refined, eclgrm.refined | ~10 min |
