New usecase.... Need help with pixhawk

Hello all,

I am working on a new usecase.

  1. Drone with Pixhawk needs to travel in autonomous mode
  2. Land at a pre selected location.
  3. Turn off propellers rotation and wait
  4. Switch on propellers and return to initial location.

Can we do this with pixhawk? Do I need to fit raspberrypi? How can I program this?
Please let me know any relevant information that can help me solve use case
