Geolocation

Geolocation is implemented as an ChirpStack Application Server integration. ChirpStack Network Server simply forwards the 'fine-timestamp' (if available) when it receives an uplink.

Requirements

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, ChirpStack Network 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.
