Earth wgs84
WebWGS84 combines the old GRS 80 with the then-latest data, namely available Doppler, satellite laser ranging and Very Long Baseline Interferometry ( VLBI) observations, and a new least squares method called collocation. [3] WebEarth radius (denoted as R 🜨 or ) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 …

WGS 84 is based on a consistent set of constants and model … WebCurrently, the supported surface models are WGS84 for the Earth, MOON_SCS for the Moon, and CUSTOM_SURFACE for other celestial bodies. CUSTOM_SURFACE requires the equatorial and polar axes to be specified in meters. The only world frame currently supported is ENU.
