I've been playing with some very expensive/accurate (down to single-ns-level) GPS receivers lately.

But I wanted to see how a cheap ($10) USB receiver would fare... and it's easy enough to just connect to it from my Mac! Blog post with the details: https://www.jeffgeerling.com/blog/2025/trying-out-cheap-usb-vk-172-gps-dongle-on-mac

@geerlingguy the timing of this 😅

I was looking for exactly that sort of thing: just a simple and inexpensive GPS receiver

@hexaheximal It is quite simple... and quite inexpensive. Perfect! :D
@geerlingguy Also, the last person I asked for recommendations on what to buy recommended using something based on a u-blox chip, which that happens to have as well. Interesting!
