Hello,

Firstly, sorry for my english, I am french!

I have to create a very accurate gps and guidance system:

Centimetric accuracy (I think to DGPS or RTK)
Designed for small surfaces (dozen km² max)

After some researches on the web, I have concluded that I have to use a classical portable GPS, added to a fix station => DGPS protocol.

But I have a few questions:
What is the difference between DGPS and GPS RTK ?
Which equipment should I use?

Thank you very much for your help.

DGPS won't do it, RTK is what you need, it's been discussed here before, type RTK in one of the forum's search engines, google or buil-in search to catch up with them.
