What is CANaerospace?

Unmanned and Remotely Piloted Aircraft Systems are a conglomerate of complex and safety-critical avionic components, and the complexity of its avionic and ground systems is rising exponentially. The main differences between manned and unmanned/remotely piloted aircrafts in terms of avionics are the spatial separation of flight control system and engine components from its human machine interface and flight control input components. Communication between ground station and airborne components should to be keept as simple as possible to avoid increasing complexity of the architecture and costs.

Safe and reliable communication between airborne and ground components are the key challenge for reducing sources of safety hazards in practice. The important factors of avionics buses include: Deterministic behavior, Fault tolerance, and Redundancy. A standard serial avionic bus should be adopted from the early beginning of the development of unmanned/remotely piloted systems to enhance:

  • Return on Investments (ROI)
  • Lowering Total Cost of Ownership (TCO)
  • Hardware in Loop (HIL) Simulation
  • Test rigs
  • Maintenance
  • Manufacturer interoperability

Different avionic bus standards exists today, but most of them are obsolete, expensive and not well suited for modern unmanned/remotely piloted systems new requirements.

CANaerospace, a modern and cost effective alternative to ARINC 429 and MIL-STD-1553 avionics buses, is an extremely lightweight protocol/data format definition which was designed for the highly reliable communication of microcomputer-based systems in airborne applications via Controller Area Network (CAN). The purpose of this definition is to create a standard for applications requiring an efficient data flow monitoring and easy time-frame synchronisation within redundant systems. The definition is kept widely open to allow implementation of user-defined message types and protocols.

CANaerospace Education & Integration Competence Center

The RPAS Experts CANaerospace Education program is designed to qualify the novice through to the most qualified avionic engineer for correct integration of the CANaerospace protocol stack. The course is divided in both theoretical and practical part using the CANaerospace XCT Analyzer and Traffic Generator software and real CANaerospace avionic components. The 2-day training class are held in Peschiera d/G or on request on customer site.

The RPAS Experts CANaerospace Integration Competence Center is the focal point for CANaerospace compliancy & interoperability qualification of avionic Hw/Sw components. Manufacturer can use the RPAS Experts CANaerospace Lab Test Rig to qualify avionic and payload products in a simulator environment. A Certificate of Compliancy (CoC) will be issued after extensive lab and in-flight (where required) testing.
