Aerospace Real-Time Control Systems and Software

• Aerospace systems, including aircraft, missiles, and spacecraft use control systems to guide, navigate, and control (GN&C)
• Real-time software is crucial in aerospace systems due to the safety-critical nature of the systems
• Control system engineers play an increasingly important role in system development and integration
• The role of control system engineers has expanded with technology advancements
• Increased complexity of systems requires control system engineers who have expertise in software and systems architecture
• Modern aerospace systems heavily use software for implementation of complex control algorithms
• Typical aerospace control systems follow a sensor/computer/actuator/user interface architecture
• Layered architecture is a common design approach for aerospace control systems
• Distributed versus centralized architectures are important design variations
• Integrated Modular Avionics (IMA) is a significant advancement in aerospace control system architectures
• IMA integrates multiple systems into a uniform network of computers
• IMA reduces development costs and improves safety, as well as reduces hardware cost and weight
• System architecture development is driven by functional/performance and quality attributes
• Iterative development processes are preferable over the traditional waterfall process
• Software architecture design is a key activity for aerospace systems
• Modern aerospace systems require thorough process simulation and verification/validation (V&V)
• Key stages in the software development life-cycle (SDLC) and V&V efforts include simulation, test, and verification

Software Architecture of Aerospace Systems

• Layered architecture is a common approach in software design for aerospace systems
• The infrastructure layer contains essential software modules
• The hardware level integrates components that interact with the outside world such as sensors, actuators, and user interfaces
• Model-driven and model-based development is beneficial for aerospace software systems
• Software reuse is more than just code reuse, it also includes reuse of requirements, designs, documents, test cases, and other aspects
