Hello, I hope you can help me. We want to implement TDoA localization using four gateways that we’re going to build with the RAKWireless 5146 concentrator, which has a fine-grained time stamp. I have two questions:
-
To enable the included GPS, do I need to perform any additional configuration process after installing the system? How can I tell if the GPS is working? Is there an LED that indicates its status?
-
Is it necessary to have the GPS enabled to obtain the fine-grained time stamp?
I’d like to tell you that we currently have a gateway connected to TTN and are successfully receiving data from some end devices. However, the time stamp format it gives me is 3978862138. I don’t think that’s the fine-grained time stamp I need for TDoA.
