 |      IERS data correction        |          Orekit         |All frame transforms support the full set of IERS Earth Orientation Parameters corrections, including of course the large DUT1 time correction, but also the smaller corrections to older IAU-76/80 or newer IAU-2000/2006 precession nutation models as well as the polar wander. The frames level accuracy is at sub-millimeter level
 |     Grid-post elevation model    |          Rugged         |Only raster elevation models are supported
 |Triangulated Irregular Network elevation model | Not supported |If vector elevation models are needed, they must be converted to raster form in order to be used
-|         Geoid computation        |     Not in version 1    |The first version only supports Digital Elevation Models computed with respect to a reference ellipsoid. If needed, this feature could be added after version 1, either at Rugged or Orekit level, using Orekit gravity fields
+|         Geoid computation        |     Orekit   |Rugged expects the Digital Elevation Models to be provided with respect to a reference ellipsoid. Orekit can be used to convert a geoid-based DEM to an ellipsoid-based DEM, directly from any gravity field
 |  Time-dependent deformations     |     Interface/Rugged    |Simple line-of-sight models (typically polynomial) can be used
 |           Calibration            |Image processing or interface|The calibration phase remains at the mission-specific caller level (pixels geometry, clock synchronization …), the caller is required to provide the already calibrated line of sights
 |         DEM file parsing         |         Interface       |The elevation models are dedicated to the mission and there are several formats (DTED, GeoTIFF, raw data …).Rugged only deals with raw elevation on small latitude/longitude cells

 ### Has Rugged already been used?
 
-Almost, as it is used in a project under development.
-
-The first operational use of Rugged will be Sentinel 2 ESA mission.
-Rugged is used in the Image Processing Facility.
+Yes. Rugged is used operationally in the Image Processing Facility
+of the Sentinel 2 ESA mission, which was launched in June 2015.

 to configure Orekit to load data.
 
 Configuring data loading is explained in the configuration page For a start, the simplest configuration
-is to download the orekit-data.zip file from the download page and to either set the "orekit.data.path" Java
-property to this file or to manually configure the DataProvidersManager to use it. This example archive file
-contains the required UTC-TAI history file among others. Configuring Orekit to use this archive file can be done
-by keeping the file as a zip archive and pointing to this archive, or by unzipping it and pointing to the unzipped folder.
-
-Here is an example using the file in zip format:
-
-    DataProvidersManager.getInstance().addProvider(new ZipJarCrawler(new File("/path/to/the/zip/file/orekit-data.zip")));

-Here is an example using the folder resulting from expanding the archive:
+is to download the orekit-data.zip file from the Orekit project download page, to unzip it anywhere you
+want, note the path of the orekit-data folder that will be created and add the following lines at the start
+of your program:
 
-    DataProvidersManager.getInstance().addProvider(new DirectoryCrawler(new File("/path/to/the/folder/orekit-data")));
