Fast error analysis of continuous GNSS observations with missing data
One of the most widely used method for the time-series analysis of continuous Global Navigation Satellite System (GNSS) observations is Maximum Likelihood Estimation (MLE) which in mostExpand
Fast error analysis of continuous GPS observations
It has been generally accepted that the noise in continuous GPS observations can be well described by a power-law plus white noise model. Using maximum likelihood estimation (MLE) the numericalExpand
Angular velocities of Nubia and Somalia from continuous GPS data: implications on present-day relative kinematics
Abstract This study focuses on the break-up of the African tectonic plate into separate Nubian and Somalian blocks, based on recent Global Positioning System (GPS) data. A new, unique velocity fieldExpand
The relative motion between Africa and Eurasia as derived from ITRF2000 and GPS data
[1] Studies of intra- and inter-plate deformation typically need a model describing the motions of the stable part of the tectonic plates for reference purposes. We have developed DEOS2k, a model forExpand
Monitoring Sandy Shores Morphologies by DGPS—A Practical Tool to Generate Digital Elevation Models
Abstract The highly dynamic nature of some sandy shores with continuous morphological changes require the development of efficient and accurate methodological strategies for coastal hazard assessmentExpand
Surface velocity field of the Ibero-Maghrebian segment of the Eurasia-Nubia plate boundary
SUMMARY We process continuous GPS data distributed over the Iberian Peninsula, complemented by a few stations in France and North Africa, to constrain the displacement field in the surroundingExpand
The effect of temporal correlated noise on the sea level rate and acceleration uncertainty
It is well known that sea level variations exhibit temporal correlation. This is sometimes ignored in the estimation process of the sea level rise or taken into account using a first-orderExpand
Defining the plate boundaries in the Azores region
Abstract The Azores Archipelago occupies the boundary zone where three major tectonic plates (Eurasia, Nubia, and North America) meet to form the Azores Triple Junction. Repeat observations from sixExpand
Persistent Scatterer InSAR: A comparison of methodologies based on a model of temporal deformation vs. spatial correlation selection criteria
In this paper, two Persistent Scatterer Interferometry (PSI) methodologies are compared in order to further understand their potential in the detection of surface deformation. Expand
The influence of seasonal signals on the estimation of the tectonic motion in short continuous GPS time-series
Abstract Most GPS time-series exhibit a seasonal signal that can have an amplitude of a few millimetres. This seasonal signal can be removed by fitting an extra sinusoidal signal with a period of oneExpand
