IERS Conventions 2010. IGS Data Reprocessing Campaign. GGFC - Global Geophysical Fluid Center. 2nd IGS Data Reprocessing Campaign. GPS stn info: GGFC - Global Geophysical Fluid Center. Here we provide global grids of loading derived from the NCEP (National Center for Environmental Protection) Reanlysis surface Pressure data set.
This is a GGFC Operational Product Data sets here are updated as often as the NCEP data are updated. The 3-dimensional displacements have been derived using the method originally outlined in van Dam and Wahr [1987]. (van Dam, T. and J. Wahr, , Displacements of the Earth's surface due to atmospheric loading: Effects on Gravity and Baseline Measurements, J. Deviations from that procedure include: Determination of the ocean mask: In van Dam and Wahr [1987], a 2.5 X 2.5 degree land/ocean mask was used. The data are first organized by reference frame. Each individual file contains the global (2.5 deg.
Each file can be read using the following algorithm (or something equivalent) where dvt is surface displacement to the north, dvl is surface displacement to the east, and du is surface displacement in the radial direction: National Geodetic Survey - Antenna Calibrations. IGS_AC_ops_status.

Rudi Stöger stoeger at fs.wettzell.de Wed Sep 14 07:27:08 PDT 2011 Author: Rudi Stoeger Ladies and Gentlemen When my colleagues installed the TPSCR.G3 antenna and the TPSH radome in the OHI2 GPS+GLONASS Permanent Tracking Station in the German Antarctican Receiving Station in O'Higgins, 2009-01-30, they did a survey and reported the antenna height (Marker->ARP Up Ecc) with 000.0375 m.

Since 2009-01-30 the antenna height is 000.0375 m in the OHI2 Site Information Form (site log) and in the RINEX Header. My colleagues removed the same antenna and the radome for a refurbishment of the pillar and for a local survey, 2011-02-07, 13:45 UT. Same day at 20:00 UT they installed the antenna and radome again. My colleagues reported: "No change in the antenna height". More information about the IGSSTATION mailing list.
GIPSY Automatic Precise Positioning Service - APPS. The GPS Toolbox. GPS Explorer Portal. Finite-fault slip model for the 4/4/2010 Mayor-Cucapah Earthquake created from 3-D coseismic vectors Welcome to GPS Explorer New Please help us celebrate Scripps Orbit and Permanent Array Center's (SOPAC's) 20th Anniversary, help contribute to its continuation for many more years, and help us improve SOPAC services, by taking a few minutes to complete our survey.
We hope that SOPAC has been a valuable resource to you and your research/business and we invite you to express that in the survey. The survey will ask you about usage and value of the SOPAC archive, web applications, and GPS Explorer Data Portal. The GPS Explorer data portal provides tools to access and explore GPS data, positions, time series, velocities, and strain from continuous GPS stations covering Western North America. GPS Explorer contains interactive utilities for selecting sites, displaying time series, mapping velocities and viewing strain. Getting Started About GPS Explorer Data Products Data Product Table.
