Newcommer with an idea about gps mapping

Hi, im new here and new to TTN. Im am trying to make a mesh network of location devices that share their locations with each other while in use. My plan is to use a raspberry pi with a GPS hat, this then shares data with the other using a LORA module, to broadcast the packets. I’m currently struggling with how to store and view the maps when not connected to the internet. But before I spend more time on this i thought id pose the question, do i need a TTN gateway to connect these up or would it be possible with multiple identical node devices.

This would be LoRa point to point or point to multipoint with a mesh
overlay… not LoRaWAN and not TTN relevant and therefore way outside scope and support of this Form, sorry

thank you :slight_smile:
