EUMETSAT Polar System - Second Generation

The EPS follow-on system (EPS-SG) will provide continuity of observations and respond to the needs of the users in the 2020–2040 time frame.

EPS-SG represents Europe's contribution to the future Joint Polar System (JPS), which is planned to be established together with the National Oceanic and Atmospheric Administration (NOAA) of the United States, following on from the Initial Joint Polar System (IJPS).

Polar orbiting satellites, due to their global coverage and of the variety of passive and active sensors that can be deployed from Low Earth Orbits, have the most significant positive impact on Numerical Weather Prediction (NWP). The Initial Joint Polar System (IJPS), shared by EUMETSAT and NOAA, currently accounts for around 45% of the total error reduction on Day 1 forecasts achieved by all types of observation ingested in real-time by NWP models.

Polar orbiting satellites also deliver unique infrared and microwave imagery inputs to critical nowcasting of high impact weather at high latitudes. These are vital for the National Meteorological Services of all EUMETSAT Member and Cooperating States.

The EPS-SG Programme is expected to be one of the most important sources of satellite observations for all forecasts based on NWP in the 2020–2040 time frame. It is expected to increase direct socio-economic benefits to Member States and leverage additional benefits through its integration into the JPS and cooperation in the context of CGMS and WMO.

The European Space Agency will develop the Metop-SG satellites and a number of instruments, with CNES and DLR developing some of the key instruments.

EUMETSAT will provide the launch and LEOP services and operate the satellites for a nominal duration of 21 years.
