GPS Module(s) on Peplink Products?

I’m unable to find detailed information regarding the GPS modules used on-board peplink products. I am primarily interested in positional accuracy for the Transit Duo. But it would be nice to understand the GPS specifications across all product lines.

Does anyone have access to this information?

As far as I know it’s build in to the sierra modem. You can look at the engineering data on the cellular tab under the ? icon.
