  • [ANN]: Copilot 3.10 - Runtime monitoring
    3 projects | /r/haskell | 14 Jul 2022
    Copilot is being used by the Safety-Critical Avionics Systems Branch (D320) of NASA Langley Research Center to conduct experiments related to flight safety of aerial vehicles. We have also built Ogma [3], a tool that allows us to generate full monitoring applications (e.g., NASA's Core Flight System [4] applications) from requirements in structured natural language.

    Understanding these properties can get hard. Using a high level language as opposed to just C is very helpful (we review the code of flight systems with sometimes 4-5 people in the room and it's not trivial at all what it is doing or to show that it is correct). But even streams can sometimes be hard to understand for very complex monitors. We've also built Ogma ( so that people can write properties in structured natural language, or transform other languages into Copilot (and then C/whatever).
