Geostationary Satellite View (Google it)

Documented in document CGMS 03 (Coordinate Group for Meteorological Satellites - LRIT/HRIT Global Specification). Possibly availble at url http://www.eumetsat.int/en/area4/msg/news/us_doc/cgms_03_26.pdf. The GEOS projection is detailed in section 4.4.3.2. The document suggests a spheroid with a major axis of 6378169.0m and a semi minor axis of 6356583.8m. The document describes the satellite height as distance from the satellite to the center of earth, but for various reasons I have chosen to specify it as height above the ellipsoid in the WKT (and in PROJ.4). The document suggests a height of 42164000m which on the suggested ellipsoid translates to 35785831m above the ellipsoid.
