Why is RAK7249 bundled with GPS?

Hi, I see that the RAK7249 DIY Gateway has GPS input.

However it has NTP client so it can get accurate time over the network. [1]
It would need even better GPS time if it support localization but I read that it does not. [2]

So why should I add GPS antenna to the gateway? What purpose does it have? Thanks!

Does RAK7249 Bundle Pro - AU915 support it? - Hello, It does not support it, none of our Gateways do. Regards Vladislav” https://store.rakwireless.com/products/rak7249-diy-outdoor-gateway

I really need it since I’m using it for different locations. That way I don’t need to remember to update it’s coordinates. TTN utilize the GPS coordinates as well and the price of adding the hardware for it doesn’t add much to the cost. I like it.
