Forgive me if this has been discussed previously...
Visiting my daughter over the holidays, a person who loves her dogs, she mentioned the collars they have that notify an app on their phones when the dogs go away from their house and give their gps locations. I was thinking they have to be using a cell network for this, and then I was thinking this would be great for rocketry use if your launch field is within cell network range. You would get gps coordinates on your phone when the rocket lands! I don't think they are overly expensive since they are made for dogs and not for a limited hobby like rockets.
