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

A Worldwide Ionospheric Model for Fast Precise Point Positioning
IEEE Transactions on Geoscience and Remote Sensing, 2015 Fast precise point positioning (Fast-PPP) is a satellite-based navigation technique using an accurate real-time ionospheric modeling to achieve high accuracy quickly. In this paper, an end-to-end performance assessment of Fast-PPP is presented in near-maximum Solar Cycle conditions; from the accuracy of the Central Processing Facility corrections, to ...

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.
