~1m accuracy with affordable GPS module? (Europe)

Hi there,

Is there any way to achieve a ~1m accuracy with GPS modules < 50 EUR (in Europe)?
I'm not very familiar with Galileo/Glonass and other options.

Thank you!

You need differential GPS, each receiver is probably > €50 and you need two, base station and
roving. I found this: Low-cost centimeter accurate satellite positioning (GNSS/GPS) - Robotics Stack Exchange

But that's probably out of date - perhaps a GPS forum is what you need, not an Arduino forum?
