13.3. Geocentric Position
Summary: The Geocentric World Position object provides a simple location
feature for radio and transmitter positioning.
Description: The World positions of the transmitter and receiver are used to
compute the diminishing power, as well as occulting by the earth for line of sight
transmissions. The standard model of the earth is a smooth ellipsoid a terrain server
maybe used for accurate modeling.
The Geocentric World position is identical to the Geodetic World Position, except
that the input values for the position are given in terms of X, Y, and Z coordinates
from the center of the Earth in meters.
If the world position is 0, 0, 0 (i.e. the center of the Earth), then the ranging effects
of any attached radio are turned off and the radio will clearly receive all
transmissions on its frequency.
