Hi @beyoungglh,

thanks for sharing your thoughts and being willing to collaborate. I'm currently working on validating the architecture in real test flights and have little time for updating the docs. I'll try my best to do this in the future 🙂

In the mean time, make sure to read https://www.scitepress.org/Papers/2024/129515/129515.pdf

Also have a look at the auto_apms_mission package and the example referenced in the README.
