How would you even configure [that](https://www.thethingsnetwork.org/forum/t/gateway-gps-configuration-in-local-conf-json/6176) in the TTN Gateway? And even with a GPS in the gateway (and assuming it would get a proper fix indoors), how would TTN Mapper know where _the node_ is?

Like @sronan wrote: just set the location in TTN Console: Gateways, select yours, Settings, Location. It will take some time before the location is propagated to [https://www.thethingsnetwork.org/map](https://www.thethingsnetwork.org/map) so maybe it takes some time for TTN Mapper to know its location too—I don’t know.
