The development of unmanned vehicles within the ground-, sea- and air domains has accelerated the last decade and numerous international exercises are being performed where operational experimentation with unmanned systems is an integral part. This report provides a summary description of the research activities that have been performed within the project Unmanned vehicles and autonomous systems - technology and organisation during 2021. The project includes work packages with the aim of building knowledge within critical technology areas, such as robust PNT-systems (Position, Navigtion, Time), automatic error detection and handling, and a comprehensive technology overview of unmanned systems suitable for air operations and swarming. Also, research targeting ethical and legal aspects concerning the use of remotely operated weapon systems on unmanned vehicles, and studies of mannedunmanned teaming and user interfaces for efficient control of unmanned vehicles, are being pursued. The research within these areas continues during the upcoming years and results will be reported continuously within each work package. The aim is to use the knowledge obtained through this research to improve the Armed Forces concept development within the broad area of unmanned vehicles and autonomous systems.
