DGPS see Differential GPS .
Differential GPS (DGPS) a positioning procedure
that uses two receivers, a rove
location and a reference station at a kno
location. The reference station computes
based on the actual and observed ranges to the
satellites being tracked. The coordinates of the
unknown location can be computed with sub
level precision
satellite data received by the rover.
Dilution of Precision (DOP) a class of measures of
the magnitude
the orientation of the GPS satellites with resp
the GPS receiver. There are several DOPs to
measure different components of the error. Note: thi
is a unitless value. see also PDOP.
