The global satellite network coordinated through CGMS constitutes a major part of the space-based component of the WMO Integrated Global Observing System (WIGOS). WIGOS provides observations of the physical state of the Earth system from both space- and surface-based observing systems, supporting the sustained and cost-effective delivery of weather, climate, water and related environmental services by WMO Members.
The CGMS Baseline sets out the commitments and plans of CGMS Members to provide observations, measurements and services in support of WIGOS. The coordinated services include data access, direct broadcast, data collection and validated geophysical products.
CGMS Members will take steps to ensure continuity of the CGMS Baseline by following the guidelines outlined in the CGMS Contingency Plan.
Satellites currently contributing to the CGMS Baseline are listed on the satellite status page maintained by the WMO Space Programme Office on behalf of CGMS. The tables provide the current status of on-orbit satellites, as well as plans for future satellites, including launch dates, orbital characteristics, payloads and, where relevant, operational status. Hyperlinks provide access to more detailed information from OSCAR/Space, including information on instruments, satellites and high-level gap analysis. Information is available for both operational and research and development satellites in geostationary, highly elliptical, sun-synchronous and drifting orbits that contribute to WIGOS. OSCAR/Space and the satellite status page are regularly updated based on information provided by satellite operators. Please note that satellite status and plans may evolve over time. Neither WMO nor CGMS is liable for the consequences of any inaccuracies that may be found in these tables.
