LoRa Server supports geolocation by using an external geolocation-server service. You can either use the geolocation-server provided by the LoRa Server project, or implement your own (matching the expected api).


For using geolocation, you need to use gateways that are capable of providing a “fine-timestamp”. Some of these gateways encrypt this fine-timestamp.

Decrypt fine-timestamp

When configuring the per gateway and board specific decryption key, LoRa Server will decrypt the fine-timestamp, before forwarding it to the geolocation-server. For getting this fine-timestamp decryption key, please contact your gateway vendor or Semtech.

Device location

When LoRa Server (using the geolocation-server) is able to resolve the location of the device, it will forward this to the application-server.
