Furthermore, I stumble upon an article about a module with u-blox

<p> Does anyone have any experience with modules like this and

There are some uBlox modules that can be had for under 10$US from
AliExpress. These are as barebones as you can get. They're just a
GPS receiver, nothing more. You need power, you need something to
read the output. On the other hand, if you're into experimenting
they're dirt cheap. I used on to build a very basic data logger
using a $2 microcontroller to write to a flash card. Some of the
cheap uBlox modules can output carrier phase data so you could use
RTK to get sub-meter resolution, at least in theory. Doing this in
real-time in the field strikes me as hard, but you could collect the
data and post-process after the fact to get accurate field
positions. <br>
