EPS-SG consists of two, parallel series of satellites (Metop-SG A and Metop-SG B).
- The Metop-SG A series has the optical imaging, infrared and microwave sounding; aerosol imaging, and radio occultation missions. It also hosts the Copernicus Sentinel-5 mission.
- Metop-SG B series is dedicated to microwave and sub-millimetre-wave imaging, scatterometry and radio occultation. It also hosts the ARGOS data collection system.
The plan is for a series of three satellites of each type (six in total) and a constellation deployment scenario allowing parallel operations of multiple satellites.
