Pierre Augera Observatory is the largest project in the field of ultra-high-energy cosmic radiation detection. In twelve years of operation, many questions were answered which motivated the construction, but many others have arisen. The Czech teams participated in the construction and operation of the observatory from the very beginning. The aim of this project is to ensure the continuation and deepening of international cooperation in the field of data analysis and detector function and to equip the laboratory in Prague so that it is possible to contribute to the upgrade of the observatory. a.
