What techniques improve GPS accuracy?
Systems that enhance positional accuracy are: the DGPS (Differential GPS), AGPS (Assisted GPS), RTK (Real-Time Kinematic), e-Dif (extended Differential), amongst others. The DGPS corrections service has two hard restrictions: it must be afforded and the receiver must be close to a DGPS station (less than 1000 km).

How can the accuracy of the GPS be improved?
you have to be prepared to use a bit more battery than normal.
