Overview of the EPS-Sterna Program
The EUMETSAT Polar System (EPS)-Sterna program represents a significant advancement in satellite technology aimed at improving weather forecasting and climate monitoring. Fully funded by EUMETSAT’s 30 member states, the program will deploy a constellation of 20 micro-satellites designed to enhance global microwave sounding coverage, particularly addressing observation gaps in the Arctic region. The first six satellites are scheduled for launch in 2029, with the entire mission expected to last 13 years.
Economic Impact and Benefits
The EPS-Sterna program is projected to generate over €30 billion in value for Europe, yielding a benefit-cost ratio of up to 51:1. This data will enable national meteorological services to enhance their forecasting capabilities, ultimately aiding in decision-making processes that protect lives, infrastructure, and economic activities. Phil Evans, Director-General of EUMETSAT, emphasized the program's role in risk anticipation and economic resilience, stating, “EPS-Sterna strengthens our ability to anticipate risks, protect citizens and support resilient economies.”
Development and Collaboration
The contract for satellite production was signed between OHB Sweden and the European Space Agency, marking the official commencement of the EPS-Sterna satellite development. Under this program, the European Space Agency will procure the satellites on behalf of EUMETSAT, with OHB Sweden serving as the prime contractor for the space segment. EUMETSAT will manage the ground segment, oversee launch services, operate the satellites, and distribute data through its established mechanisms, including EUMETCast and EUMETView.
International Cooperation
The EPS-Sterna program also opens avenues for collaboration with international partners, including the United States, China, and India, in support of the World Meteorological Organization’s Global Observing System. This cooperation is expected to enhance global weather observation capabilities and foster a unified approach to climate monitoring.
Official Statements
Phil Evans remarked on the significance of the EPS-Sterna program, highlighting its potential to improve weather forecasting and climate resilience across Europe. He noted, “The signature of the contract with OHB Sweden today marks the start of EPS-Sterna satellite development: it is an important milestone for Europe’s space-based observing system.”
Conclusion
EUMETSAT's EPS-Sterna program is poised to significantly enhance Europe’s weather forecasting and climate monitoring capabilities through innovative satellite technology. By leveraging international partnerships and advanced data collection methods, the program aims to provide critical support for national meteorological services and contribute to the safety and economic stability of European nations.
