I've read about how DGPS systems basically work and, as far as my research has come, it seems that it is not impossible to be reproduced.
I thought about having a fixed GPS in a location I know where it is (let's suppose I know it by clicking on the exact position it is on google maps and seeing it's coordinates). I measure my object's position with it's GPS system as well as the fixed base. Knowing where my base is, I know the error of the GPS and, as long as the base and the object are close to each other, I the error on the object must be similar.
Is it right? Is there something special I should have/know?

It sounds like DIY DGPS is much harder to achieve than it appears --
