What is Copernicus for: the programme

Copernicus is a programme coordinated by ESA that ensures that Europe is constantly surveyed of the Earth’s surface and that data on the health of the planet is constantly managed from multiple sources, such as satellites. Exprivia has previously played a key role in the Copernicus programme, collaborating in the implementation of the stations. Today we are back to being protagonists of the project with a new solution for the management of data from satellites.

The archives containing Copernicus data are constantly expanding, given the large amount of information generated by the numerous space missions in progress; for this reason, ESA has questioned the capabilities of previous satellite data storage systems, thus opening up to new technologies.

Exprivia Solution

Copernicus Programme: Exprivia’s Long Term Data Preservation solutions

Exprivia, winner of the international public tender launched by ESA, was the first company to develop, together with its partners, a Long Term Data Preservation (LTA) system based on optical discs in the Aerospace sector. It is an archive that allows the long-term preservation of large amounts of data from satellites, for over 100 years. The archive stores a conspicuous flow of raw data, which are the basis of the information and constitute a heritage of fundamental importance for monitoring the health of planet Earth.

The revolutionary system for archiving raw data – captured directly from the satellite – uses the new ODA GEN3 optical media, the third generation of Sony’s Optical Disc Archive technology , a system aimed at the long-term archiving segment for Big Data storage.

ODA technology for advanced satellite data storage

Thanks to ODA, for the next 100 years an immense amount of information (more than 8 Peta Bytes at the end of 2021) from Earth observation and monitoring will be stored in devices that are more performing and durable than traditional magnetic media.

The LTA service records a daily flow of about one Terabyte (TB) of data for each satellite from the European “acquisition-and-processing” centers, extracts the metadata and stores it on-line, near-line and off-line. Once processed at higher levels, the data will be available free of charge to citizens, public and private bodies (including research institutes, military or government authorities) and authorized companies that request it.

Results

Multi-industry data storage and protection technologies

The solution proposed by Exprivia will make it possible to catalog, control and index Copernicus data, ensuring their conservation and future retrieval. And together with Sony’s ODA technology , it ensures reliability and safety, helping to inform us about our planet’s environmental, terrestrial, meteorological and atmospheric phenomena for decades to come.

A new approach that will make useful information available to future generations free of charge to protect the Earth. This technology is now available not only for the Aerospace sector, but also for other contexts in the IT world, for the protection of heterogeneous databases in markets such as Industry, Healthcare, Public Administration and the Banking world.
