Jun 3, 2024 · ITRF08 Is the International Terrestrial Reference Frame of 2008 that improved on ITRF05. It is based on reprocessed solutions of four geodetic techniques—Very Long Baseline Interferometry (VLBI), satellite laser ranging (SLR), GPS, and Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS), spanning up to 29 years of ...

ITRF2008 is the new realization of the International Terrestrial Reference System. Following the procedure already used for the ITRF2005 formation, the ITRF2008 uses as input data time series of station positions and EOPs provided by the Technique Centers of the four space geodetic techniques (GPS, VLBI, SLR, DORIS).

The objective of this web site is to distribute the International Terrestrial Reference Frame (ITRF) products. ITRF94, ITRF96, ITRF97, ITRF2000, ITRF2005, ITRF2008, ITRF2014, ITRF2020 and ITRF2020-u2023 solutions are available for download. It also contains the description and list of all the IERS stations.

New ITRF solutions are produced every few years, using the latest mathematical and surveying techniques to attempt to realize the ITRS as precisely as possible. Due to experimental error, any given ITRF will differ very slightly from any other realization of the ITRF.

In their new definitions—NAD83 (2011) and WGS84 (G1762)—differ up to one or two meters within the continental United States. On the other hand, ITRF08, ITRF2014 and WGS84 (G1762) are virtually identical if their epochs (moment in time) are the same. The typical standard epoch for both are WGS84 (G1762) and ITRF08 is 2005.0.

Feb 3, 2011 · ITRF2008 is a refined version of the International Terrestrial Reference Frame based on reprocessed solutions of the four space geodetic techniques: VLBI, SLR, GPS and DORIS, spanning 29, 26, 12.5 and 16 years of observations, respectively.

May 17, 2019 · EPSG:5332 Geocentric coordinate system for World. Replaces ITRF2005 (CRS code 4896). Replaced by ITRF2014 (CRS code 7789). Geodesy.

Las técnicas aplicadas para la definición de ITRF2008 y la cantidad de estaciones disponibles en todo el mundo, permitieron obtener altos órdenes de exactitud en la determinación de las …

On April 17, 2011, the International GNSS Service (IGS) stopped using the IGS05 reference frame and adopted a new one, called IGS08, as the basis of its products. The latter was derived from the latest release of the International Terrestrial Reference Frame (ITRF2008).

Sistema de consulta de las coordenadas geodésicas de las estaciones de la Red Geodésica Nacional Activa en el marco geodésico de referencia oficial denominado ITRF08, a la época 2010.0, así como sus características técnicas, necesarias para el procesamiento geodésico.
