\section{ECEF}
|
|
Earth-Centered-Earth-Fixed coordinates belong to the easiest coordinates to compute, because they have a fixed frame and they don't have to regard the non-spherical shape of the earth. Though they are not intuitiv. \\

ECEF coordinates are defined using
|
|
\begin{equation}
|
|
p_{ECEF} = \begin{pmatrix} x \\ y \\ z \end{pmatrix}
|
|
\end{equation}
|
|
available for the following simple types
|
|
\begin{itemize}
|
|
\item int32\_t - \texttt{EcefCoor\_i}
|
|
\item float - \texttt{EcefCoor\_f}
|
|
\item double - \texttt{EcefCoor\_d}
|
|
\end{itemize}
