Data Format

The data specifies for each data point an ID, Earth Centered Earth Fixed (ECEF) X,Y,Z coordinates, a description and optionally an EGM96 Elevation in this order. Some parameters at the begin of the data control the GNSS Data Viewer.

ECEF: (Earth Centered, Earth Fixed) is an orthogonal coordinate system, that has the origin on the mass center of the earth, X axes pointing to the 0-meridian, X/Y plane in the equatorial plane, Y axes pointing to east longitude 90° and Z axis pointing to the north pole. The coordinates are expressed in meters.

EGM96: (Earth Gravitational Model 1996) is a geopotential model of the Earth consisting of spherical harmonic coefficients complete to degree and order 360. The EGM96 model defined the Geoid heights for the whole world.

Elevation: The elevation here is the height of a data point above or below the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface, see Obtaining Elevations (Destination PageRainy Lake Experiment: Location Graph and Data).
