This document provides Minimum Aviation System Performance Standards of Remote Pilot Stations (RPS) for Remotely Piloted Aircraft Systems (RPAS) within EASA’s Certified Category, with the focus on Air Traffic Integration (ATI) requirements for IFR operation in controlled airspace. The RPS and its operational context is fully defined in the Operational Services and Environment Definition (OSED). This standard specifies system characteristics, when it is composed of several individual components. It should be useful to designers, manufacturers, installers, service providers and users for systems. Where systems are global in nature, the system will have international applications which are taken into consideration. It is also driving the development of subsequent MOPS by proving a clear allocation of the system performances between its various individual components.
