Modeling tropospheric wet delays with dense and sparse network configurations for PPP-RTK
P. S. Oliveira,Laurent Morel,F. Fund,R. Legros,João Francisco Galera Monico,Stéphane Durand,Frédéric Durand +6 more
TL;DR: In this paper, a real-time precise point positioning (PPP) in real time is presented, where the ZWD estimates at Orpheon GNSS reference network stations are used to model the behavior of the troposphere over France.
Sentinel-1 for monitoring tunnel excavations in Rennes, France
Abdeljalil Nahli,Elisabeth Simonetto,Véronique Merrien-Soukatchoff,Frédéric Durand,Damien Rangeard +4 more
- 01 Jan 2018
TL;DR: It is demonstrated that a dense PS cover, the feasibility of small displacement scale and rate monitoring using a small set of Sentinel -1 images, and the mean displacement velocity map and displacement time series show that the detected deformations are correlated in space and in time with the excavation works.

On the relation between GPS tropospheric gradients and the local topography
Laurent Morel,Ouafae Moudni,Frédéric Durand,Joëlle Nicolas,Jean-Michel Follin,Stéphane Durand,Eric Pottiaux,Joël Van Baelen,Paulo Sergio Rabello de Oliveira +8 more
TL;DR: In this article, the correlation between the tropospheric gradients and the topography was studied using the GIPSY-OASIS II SOFTWARE from 2 years of GPS observations recorded at 52 worldwide permanent stations, focusing on regions with significant relief.

An Analysis of Displacement Measurements for Lisbon, Portugal Using Combined InSAR and GNSS Data
D. Roque,Elisabeth Simonetto,Ana Paula Falcão,Daniele Perissin,Frédéric Durand,Laurent Morel,A. M. Fonseca,Laurent Polidori +7 more

TL;DR: In this paper, the authors used the zenith total delay (ZTD) values derived from global navigation satellite system (GNSS) to correct interferograms from tropospheric effects.

Influence of GNSS Configuration and Map Interpolation Method on InSAR Atmospheric Phase Assessment
Elisabeth Simonetto,Frédéric Durand,Laurent Morel,Yassine El Hamri,Jean-Luc Froger,Joëlle Nicolas-Duroy,Stéphane Durand,Laurent Polidori +7 more

TL;DR: In this paper, the correction of interferograms using tropospheric delays measured from GNSS stations was studied and the results show that the interpolation strategy and the GNSS network geometry have a significant impact on the correction.
