Hello!
I search a gps chip to use in a project, and I'd like to know if someone knows a good one.
It must provides a 5 metre accuracy or better.
Thank you in advance for youre answear (and please forgive my terrible english
)

http://sparkfun.com has a few. This one:
https://www.sparkfun.com/products/12751 claims 2.5m accuracy.
Sparkfun also has a GPS buying guide that you should probably read through:

Thank you very much!
Must be a absolute noob question but how do you know is a gps chip is compatible with a pyboard or not?

Most GPSes that I'm familiar with have a logic level serial interface. The pyboard has 5V tolerant inputs for the UARTs so it should work with 5v or 3.3v signals.

I often look at Sparkfun and Adafruit for common products that usually offer good getting started guides.
And like Dave said GPS modules are usually 3.3 and/or 5v tolerant USARTs that are easy to interface with microcontrollers.
