DGPS see Differential GPS.
Differencing is a techn
processing to resolve the integer cycle a
reduce a number of error sources including oscillator
variations and atmospheric and orbital modeling
This technique “differences” the measurement o
carrier beat phase across time, frequency, receivers,
satellites, or any combination of these. The most
popular differences are single, double and triple.
Differential GPS (DGPS) is a positi
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
