DGPS see Differential GPS.
Differential GPS (DGPS) a positioning procedure
that uses two receivers, a rover at an unknown
location and a reference station at a known, fixed
location. The reference station computes corrections
based on the actual and observed ranges to the
satellites being tracked. The coordinates of the
unknown location can be computed with sub-meter
level precision by applying these corrections to the
satellite data received by the rover.
Dilution of Precision (DOP) a class of measures of
the magnitude of error in GPS position fixes due to
the orientation of the GPS satellites with respect to
the GPS receiver. There are several DOPs to
measure different components of the error. Note: this
is a unitless value. see also PDOP.
