Hello hikers

I am an engineering student from Denmark. I am looking to develop a drone that can assist hikers in need of help. The basic idea I am working with now is that you can deploy the drone and it will try to locate help.
Different scenarios where I imagine this could be useful:

  • You are in a place with no telephone signal. The drone knows where the nearest telephone signal can be located. In case of emergency it flies there and sends an emergency signal.
  • You fall into some hole(?) without any signal. The drone would be equipped with sensors that make it able to escape the hole and send a distress signal.

I realize that satellite phones and PLBs exist, however I believe this solution could be done a lot cheaper.

Is this a product you would be interested in? If so, why or why

Thanks in advance
