Correct LoRa Gateway for TDOA?
I am setting up a asset tracking system around my city, and recently brought a RAK Gateway and the Arduino MKR WAN 1300(end device)Before I buy 3 more which is required for TDOA(GPS-free) location can anyone please tell me if the gateway i purchased us derived from the Semtech's V2 reference design? so TDOA is possible.
to be more specific does this gateway support fine-timestamp support and can I get the license the key to decrypt this fine-timestamp as it is encrypted. This is required for TDOA localization.

Hi, I would like to know the same thing. Thanks.
To my understanding these gateways use the standard Semtech Ic's and the software that is run on them is up to you.
Any official answer?
It definitely has all hardware for it. I have tested GPS and it works well. For TDOA, GPS must provide PPS input to SX1301. You can see that connection is done with a jumper cable between GPS and gateway board. I think that this will be gateway firmware bug or it lacks this feature.
I should have been clear. i meant for a GPS-less device, to obtain location by TDOA...i had to attach a ESP8266 and do a wifi sniff to obtain signinal strength of nearest wifi...and simpled used SigFox Geolocation : https://www.sigfox.com/en/sigfox-geolocation in
my application(my application after data is sent from device to TTN). etc.
