+In this third scenario it is shown a possible way the number of visible satellites can influence the availability of the position. In figure~\ref{fig:control3} are shown the number of visible satellites and the control signal that turns on the GPS antenna. We simulate an satellites outage at $time=100$ where the number of visible satellites becomes 3 which is not sufficient for providing any positioning. The device before that tracks the 5 visible satellites and starts samling the position every 10 seconds for one second. After the satellite outage it instead stays turned on trying to fetch more sateliites. This happens only at the time instant 200 where the number of visible satellites becomes 4. After having updated again the ephemeris data the device is able to start sampling again the position, as shown in figure~\ref{fig:position3}.
