TLDR
The next generation of positioning models for positioning and data processing will depend on the design of the satellite itself, as well as on the satellite orbits it is placed in.Citations

Functional Models of Ordinary Kriging for Medium Range Real-time Kinematic Positioning Based on the Virtual Reference Station Technique
TL;DR: This study has demonstrated the usefulness of a number of Ordinary Kriging functional models where ionospheric and tropospheric delays significantly degrade the positioning quality.

Earth Orbiting Support Systems for commercial low Earth orbit data relay: Assessing architectures through tradespace exploration
TL;DR: A tradespace exploration study of the architecture of such LEO commercial satellite data relay systems, here defined as Earth Orbiting Support Systems (EOSS), and proposes a methodology to formulate architectural decisions for EOSS constellations.

Closely-coupled integration of Locata and GPS for engineering applications
TL;DR: This study identifies that proper separation and de-correlation of Locata and GPS ambiguities and better tropospheric models are essential to reach centimetre level accuracy.

VIC-PRO: Vicinity Protection by Concealing Location Coordinates Using Geometrical Transformations in Location Based Services
Ruchika Gupta,Udai Pratap Rao +1 more
TL;DR: A scheme to preserve location privacy, called VIC-PRO, is presented that fortifies the location privacy of the client alongside vicinity protection using geometrical transformations and is experimentally compared with other existing mechanisms to demonstrate that Vic-PRO is more efficient, safe against vicinity identification attack, and guarantees better user privacy in an LBS setup.
DFT-based Synchrophasor Estimation Algorithms and their Integration in Advanced Phasor Measurement Units for the Real-time Monitoring of Active Distribution Networks
TL;DR: In this paper, an iterative-interpolated DFT (i-IpDFT) algorithm is proposed to improve the performance of the Interpolated-DFT (IpFDT) method by iteratively compensating the effects of the spectral interference produced by the negative image of the spectrum and at the same time allowing to reduce the window length up to two periods of a signal at the nominal frequency of the power system.
