Thesis: Structure change: feedback Harm

Had a short discussion on the structure with Harm.

Introduce new chapter on waveforms and ways to analyse them.

Also, move the single sine period degeneracy to a separate chapter.

If the stability of the clock allows for it, the synchronisation can be performed during a discrete period.
The tradeoff between the gained accuracy and the timescale between synchronisation periods allows for a dead time of the detectors during synchronisation.

In the case that the stations need continuous synchronisation, a different route must be taken.

The main method of synchronising multiple stations is by employing a \gls{GNSS}.
This system should deliver timing with an accuracy in the order of $10\ns$ \cite{} (see Section~\ref{sec:grand:gnss}).
