V2.0.0-FormalATM-v2.6.2 (January-31-2018)

Version 2.0 of ICAROUS, a.k.a., ICAROUS-2

• ICAROUS-2 stands for Independent Configurable Architecture for Reliable Operations of Unmanned Systems with Distributed On-Board Services (DOS).
• ICAROUS-2 is a software architecture intended to be independent from the middleware. It is currently instantiated with cFS, but it supports SHREC*'s SBD (cFS with DDS bus). More middleware may be supported in the future. [* SHREC is the University of Pittsburgh NSF Center for Space, High-performance, Resilient Computing]
• ICAROUS-2 modules, e.g., monitoring, detect and avoid, geo-fencing are distributed cFS applications.
• ICAROUS-2 includes a PLEXIL executive cFS application.
• ICAROUS-2 decision-making is implemented in PLEXIL.
• Support for Java is removed.

• Baseline ICAROUS functionalities for simple waypoint missions:
  • Prevent keep-in geofence violation (Bounce back and continue to next feasible waypoint).
  • Prevent keep-out geofence violation (Replan flight plan to avoid keep-out fence).
  • Detect and Avoid functionality (Autonomously avoid traffic and geofences).
  • Flight plan deviation monitoring (Autonomously returns back to nearest point on flightplan).
• Track a user defined object.
