+\section{Live GPS tracking}\label{sec:gpstracking}
+To activate Live GPS tracking you have select \mainmenuopt{View} > \mainmenuopt{Live GPS tracking}. You will get a new docked Window on the left side.
+
+You have 4 possible screens in this GPS tracking Window (see Figure \ref{fig:gpstrack_live}).
+
+\begin{description}
+ \item[(a)] \includegraphics[width=0.5cm,clip=true]{mActionToggleEditing} GPS Position Coordinates and for manually entering Vertices and Features
+ \item[(b)] \includegraphics[width=0.5cm,clip=true]{gpstrack_barchart} GPS Signal Strength of Satellite connections 
+ \item[(c)] \includegraphics[width=0.5cm,clip=true]{gpstrack_polarchart} GPS Polar Screen showing number and polar position of Satellites 
+ \item[Figure \ref{fig:gpstrack_options}] \includegraphics[width=0.5cm,clip=true]{mActionOptions} GPS Options screen
+\end{description}
+
+With a plugged in GPS-Reciever (has to be supported by your Operating System) a simple click on \button{Connect} connects the GPS to QGIS.
+A second click (now \button{Disconnect} disconnects the GPS-Reciever from you Computer.
+ 
+IMPORTANT: If you want to record your Position to a Canvas you have to create a new Vector Layer first and switch it to editable state to be able to record your track.

+
+\subsection{Position Coordinates}
+\includegraphics[width=0.5cm,clip=true]{mActionToggleEditing} If the GPS is recieving Signals from Satellites you will see your Position in Latitude, Longitude and Elevation as you can see in Figure \ref{subfig:gpstrack_main}
+
+\subsection{GPS Signal Strength}
+\includegraphics[width=0.5cm,clip=true]{gpstrack_barchart} Here you can see the Signalstrenght of the Satellites you are revieving signals from (Figure \ref{subfig:gpstrack_stren}).
+
+\subsection{GPS Polar Window}
+\includegraphics[width=0.5cm,clip=true]{gpstrack_polarchart} If you want to know where in the sky all the connected Satellites are, you have to switch to the Polar screen (Figure \ref{subfig:gpstrack_polar}).
+You can also see the ID-numbers of the Satellites you are recieving signals from.
+
+\subsection{GPS Options}
+\includegraphics[width=0.5cm,clip=true]{mActionOptions} In case of connection problems you can switch from ``autodetect`` to ``Use path/port below`` and select the path/port your GPS-Reciever is connected to.
+A click on \button{Connect} again initiates the connection to the GPS-Reciever.
+
+With the Slider ``GPS Cursor Size'' you can shrink and grow the Position Cursor on the Canvas.
+
+Activating ``Auto-add vertices`` within GPS digitizing your track will automatically be recorded in the active vector layer (of course the layer has to be in edit mode).
+
+With GPS map recenter you can decide in which way the Canvas will be updated if your recorded coordinates start either to move out of canvas or there is any change at all.
+
+Track Color and width sets the color of and the width of your drawn track.
+
+If you want to set a feature manually you have to go back to \includegraphics[width=0.5cm,clip=true]{mActionToggleEditing} ''Position Coordinates'' and click on \button{Add feature}. Also when you did not activate ''Auto-add vertices`` and want to record vertices manually you have to go back there and click \button{Add vertex}
