Relevance of PSInSAR Analyses at ITRF Co-location Sites [PDF]

open access: yes, 2023
Abstract The PSInSAR (Persistent Scatterer Interferometric Synthetic Aperture Radar) technique allows determining deformation maps over large areas. In this paper, we investigate the applicability of PSInSAR analyses for ITRF co-location sites characterized by spatial extents varying between 20 m and 3 km.

Dependence of IGS Products on the ITRF Datum [PDF]

open access: yes, 2012
Throughout its nearly two decades, the International GNSS (Global Navigation Satellite Systems) Service (IGS) has sought to align its products closely to successive realizations of the International Terrestrial Reference Frame (ITRF). This has been disruptive for IGS users at times, especially during the 1990s when some radical ITRF datum choices were ...

ITRF/LhARA conceptual design report [PDF]

open access: yes
This document, the principal deliverable of the Preliminary Activity, presents the conceptual design for LhARA to serve the ITRF. The conceptual design of the accelerator facility is presented in Chapter 2. Comparison of the laser-hybrid solution with the conventional alternatives has allowed the LhARA approach to be confirmed as the baseline design ...

Comparison of analysis strategies for the determination of the ITRF [PDF]

open access: yes, 2016
Reference systems are essential for navigation and surveying as well as for determining the shape of the Earth and its position and orientation in space. They are required for the precise determination of satellite orbits and serve as basis for Earth science applications such as measurements of the Earth's gravity field, atmosphere studies, detection ...

Rigorous combination to ensure ITRF and EOP consistency

open access: yes, 2007
The ITRF2005 is the first rigorous combination ensuring ITRF and EOP consistency, based on time series of station positions and Earth Orientation Parameters (EOPs). The objective of the presentation is the development of a combination strategy allowing to ensure the ITRF2005 and IERS 05 C04 consistency with time.
