WMO OSCAR Satellite Database
Part of the Orbital Mechanics Datasets collection on Hugging Face.
The most comprehensive international database of Earth observation satellites and instruments, maintained by the World Meteorological Organization (WMO) through their OSCAR/Space portal (Observing Systems Capability Analysis and Review Tool). Currently 1,025 satellites and 1,230 instruments from 81 space agencies worldwide.
Unlike catalogs that focus on a single agency (e.g., NASA, ESA), OSCAR provides truly global coverage of the full Earth observation satellite constellation -- from major programs like Sentinel, Landsat, and GOES to missions operated by ISRO, CMA, JAXA, KARI, Roscosmos, and dozens of smaller agencies.
Dataset description
WMO OSCAR/Space is the authoritative reference for operational meteorological and Earth observation satellites. It is used by WMO member states for gap analysis, mission planning, and coordination of the Global Observing System. Every satellite entry includes its operational status, orbit parameters, launch/end-of-life dates, physical specifications (mass, power), and a list of onboard instruments. The instrument catalog covers 24 distinct instrument classes, from moderate-resolution optical imagers and SAR to GNSS radio-occultation sounders and space lidars.
This dataset is particularly valuable for:
- Constellation analysis: mapping global Earth observation coverage by orbit type, status, and agency
- Instrument gap analysis: identifying which measurement capabilities exist, are planned, or are missing
- Mission planning: cross-referencing satellite platforms with their instrument payloads
- International cooperation studies: analyzing which agencies collaborate on which programs
- Historical trend analysis: tracking the growth of the Earth observation fleet over time
