/**
 * # Geostationary Satellite View (geos)
 *
 * **Classification**: Azimuthal
 *
 * **Available forms**: Forward and inverse, spherical and ellipsoidal
 *
 * **Defined area**: Global
 *
 * **Alias**: geos
 *
 * **Domain**: 2D
 *
 * **Input type**: Geodetic coordinates
 *
 * **Output type**: Projected coordinates
 *
 * ## Projection String
 * ```
 * +proj=geos +h=35785831.0 +lon_0=-60 +sweep=y
 * ```
 *
 * ## Required Parameters
 * - `+h`: The height of the satellite above the earth.
 *
 * ## Optional Parameters
 * - `+sweep`: Sweep angle axis of the viewing instrument, can be "x" or "y" (default is "y").
 * - `+lon_0`: Central meridian (longitude of origin).
 * - `+R`: Earth radius.
 * - `+ellps`: Ellipsoid.
 * - `+x_0`: False easting.
 * - `+y_0`: False northing.
