Differential GPS is a technique to apply a correction factor from a known location to a GPS signal. This can substantially reduce the uncertainty in the GPS location. Normally the correction signal is acquired using a special radio receiver: dgpsip allow you to receive a DGPS signal via TCP/IP, and send it to the GPS connected to your serial port.
