I'm starting a project in which I want to be able to attach a GPS module onto a drone in case the drone falls out of sight. I have a few questions as I'm researching parts for this.
My ideal specs: Small and light, maybe around the size of a quarter.
Most of the modules I see online seem small and compact, ranging from 20 to 30 dollars. They are also labeled as "receivers". Does this mean they can only determine their own position and not send it off? If so, where can I find a "data pusher"?
Are there better alternatives than GPS? Assuming the drone might crash, that could mean it won't get a clear satellite signal, so I'm open to different ideas, but I'm not sure what.
Any other helpful information you might have is very appreciated. I'm kinda walking into this blind right now, so I'm hoping I can figure something out.
