The Impact of Eclipsing GNSS Satellites on the Precise Point Positioning [PDF]

Remote Sensing, 2018
When satellites enter into the noon maneuver or the shadow crossing regimes, the actual attitudes will depart from their nominal values. If improper attitude models are used, the induced-errors due to the wind-up effect and satellite antenna PCO (Phase Center Offset) will deteriorate the positioning accuracy. Because different generations of satellites

Precise Point Positioning Technique Versus Relative Positioning

Baltic Surveying, 2020
Precise point positioning is a GNSS based positioning method that is known to regaining more precise information about major systematical errors in its functional model. This method is seen as an advanced version of the conventional absolute positioning method that is able to offer higher accuracy of the estimate parameter.
