Abstract

The basic equation which relates the range ϱ with the instantaneous position vector ϱ S of a satellite and the position vector ϱ R of the observing site reads
$$\varrho = \parallel {\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}\to {\varrho } ^S} - {\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}\to {\varrho } _R}\parallel .$$
(3.1)
In Eq. (3.1), both vectors must be expressed in a uniform coordinate system. The definition of a three-dimensional Cartesian system requires a convention for the orientation of the axes and for the location of the origin.
