It allows the observation of the territory for multiple applications: border control, intelligence, environmental of radio concealment GNSS (global satellite navigation system) are carried out to improve predictions regarding
control, protection of natural resources, military operations, verification of international treaties, surveillance atmospheric behaviors, such as rains, floods, etc. This project is led by the Space Science Institute (ICE) of the CSIC

Airbus in Spain, as the main contractor of the program, led a team of 18 Spanish companies and three PAZ shares the same orbit as the TerraSAR-X and TanDEM-X radar satellites of Airbus, forming a constellation of very
universities, so the Spanish space industry has been deeply involved in the development of its advanced active high resolution SAR satellites. Hisdesat and Airbus will jointly market this new constellation.

PAZ also allows us to substantially improve our country’s positioning within the European program for global
environmental monitoring and security Copernicus, the main initiative in the field of Earth observation led by the
European Union and the European Space Agency (ESA), being designated PAZ, as Copernicus Contributing Mission.
