A Worldwide Ionospheric Model for Fast Precise Point Positioning [PDF]
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 ...

Network based real-time precise point positioning [PDF]
Advances in Space Research, 2010 Network based real-time precise point positioning system includes two stages, i.e. real-time estimation of satellite clocks based on a reference network and real-time precise point positioning thereafter. In this paper, a satellite- and epoch-differenced approach, adopted from what is introduced by Han et al.

Position Dilution of Precision: a Bayesian point of view [PDF]
arXiv, 2020 The expected position error in many cases is far from feasible to be estimated experimentally using real satellite measurements which makes the model-based position dilution of precision (PDOP) crucial in positioning and navigation applications. In the following text we derive the relationship between PDOP and position error and we explain that this ...
