On September 23, the CTAO ACADA Collaboration achieved yet another milestone when the CTAO Central Organisation officially approved and closed out the Critical Design Review (CDR) of the Array Control and Data Acquisition (ACADA) system. The approval of the CDR, an in-depth evaluation to ensure the system design meets all the requirements of the Observatory, marks a new phase in the project, moving from testing to integrating the advanced software packages that will operate the arrays.
