Independent Configurable Architecture for Reliable Operations of Unmanned Systems (ICAROUS)

========



ICAROUS (Independent Configurable Architecture for Reliable Operations of

Unmanned Systems) is a software architecture that enables the robust integration

of mission specific software modules and highly assured core software

modules for building safety-centric autonomous unmanned aircraft

applications. The set of core software modules includes formally

verified algorithms that detect, monitor, and control conformance

to safety criteria; avoid stationary obstacles and maintain a safe

distance from other users of the airspace; and compute resolution

and recovery maneuvers, autonomously executed by the autopilot, when

safety criteria are violated or about to be violated. ICAROUS is implemented using the

NASA's core Flight Systems (cFS) middleware. The aforementioned functionalities are implemented as

cFS applications which interact via a publish/subscribe messaging

service provided by the cFS Software Bus.

### Detect and Avoid (DAA) and Geofencing Capabilities



ICAROUS integrates NASA's open source software packages [DAIDALUS](http://shemesh.larc.nasa.gov/fm/DAIDALUS)

(Detect and Avoid Alerting Logic for Unmanned Systems) and

[PolyCARP](http://shemesh.larc.nasa.gov/fm/PolyCARP) (Algorithms and Software

for Computations with Polygons). DAIDALUS provides detect and avoid

capabilities, while PolyCARP provides geofencing capabilities.
