[ANN] Copilot 3.12
Among others, Copilot has been used at the Safety Critical Avionics Systems Branch of NASA Langley Research Center for monitoring test flights of drones. It also serves as a runtime monitoring backend for the requirements elicitation tool FRET (https://github.com/NASA-SW-VnV/fret/), via Ogma (https://github.com/nasa/ogma).

[ANN] Summer Internship at NASA Ames Research Center
The student, if selected, will be working on extending our capabilities to test cFS/ROS/FPrime applications, especially those using Ogma and/or Copilot for monitoring. Both Ogma and Copilot are open-source software written in Haskell.

[ANN]: Copilot 3.10 - Runtime monitoring
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 (https://github.com/nasa/ogma) so that people can write properties in structured natural language, or transform other languages into Copilot (and then C/whatever).
