SNARF: POS | CSV
IGS05: POS | CSV
Position files contain GPS monument positions calculated from station RINEX data. The POS format files are comprehensive, while the simpler CSV format files are easily used for plotting in Excel, etc.. Data are available in both the SNARF 1.0 and ISG05 reference frames.
SNARF: CSV
Detrended position files contain the same data as the unfiltered position CSV files, but with a linear trend removed to better show position residuals. Only data for the SNARF reference frame are detrended.
Plot Viewer: TIME SERIES
Raw | Cleaned | Detrended
Time series plots of the data in the Unfiltered and Detrended CSV files, with a Cleaned plot showing detrended data with large residuals removed. Clicking on the arrow buttons on the pop-up plot window cycles through the different plot types.
