This paper presents a new concept for specifying Unmanned Aircraft Systems (UAS) flight operations that aims at improving the Area Navigation (RNAV) is a method of Instrument Flight Rules (IFR) navigation that allows an aircraft to follow any course within a network of navigation beacons, rather than navigating directly to and from the beacons. waypoint based approach, found in most autopilot systems, by providing higher level fligh plan specification primitives. The proposed method borrows the leg and path terminator concepts used in Area Navigation 1 (RNAV). Several RNAV leg types are adopted and extended with new ones for a better adaptation to UAS requirements. Extensions include the addition of control constructs that enable repetitive and conditional behavior, and also parametric legs that can be used to generate complex paths from a reduced number of parameters. The paper also covers the design and implementation of a software component that manages execution of the flight plan.To take advantage of current off-the-shelf flight control systems the constructs included in the flight plan are translated to waypoint navigation commands. In this way, the advanced capabilities provided by the flight plan specification language are implemented as a new layer on top of existing technologies. The benefits and the feasibility of the proposed approach for UAS flight plan management are demonstrated by means of a simulated mission that performs the flight inspection of Radio Navigation Aids.Keywords Unmanned aircraft systems (UAS) · Flight plan specification · Flight plan management 156 J Intell Robot Syst (2012) 67:155-181

“…SOFA HI [27] offers a metamodel for application component design. The component-based concept is also used in unmanned aircraft systems (UAS) to deal with increasing complexity of subsystems, distributed communication and management services [28]. Marco Panunzio et al [26], [29] designed a domain-specific metamodel called Space Component Model (SCM) for component models for ESA research and development projects.…”

Emerging applications for space missions require increasing processing performance from the onboard computers. DLR's project "Onboard Computer-Next Generation" (OBC-NG) develops a distributed, reconfigurable computer architecture to provide increased performance while maintaining the high reliability of classical spacecraft computer architectures. Growing system complexity requires an advanced onboard middleware, handling distributed (real-time) applications and error mitigation by reconfiguration. The OBC-NG middleware follows the Component-Based Software Engineering (CBSE) approach. Using composite components, applications and management tasks can easily be distributed and relocated on the processing nodes of the network. Additionally, reuse of components for future missions is facilitated. This paper presents the flexible middleware architecture, the composite component framework, the middleware services and the model-driven Application Programming Interface (API) design of OBC-NG. Tests are conducted to validate the middleware concept and to investigate the reconfiguration efficiency as well as the reliability of the system. A relevant use case shows the advantages of CBSE for the development of distributed reconfigurable onboard software.
