+%<<<
 Using radio antennas to detect \glspl{UHECR} has received much attention recently.
 The \acrlong{Auger} is currently being upgraded to \gls{AugerPrime} incorporating radio detectors with scintillators and water-cherenkov detectors.
 Other experiments, such as \gls{GRAND}, plan\Todo{word} to fully rely on radio detection only.

 % Timing not enough
 Time information in such large observatories is typically distributed using \glspl{GNSS}, reaching up to $10\ns$ accuracy under very good conditions.
-For analysis using radio interferometry to be competitive, this timing accuracy needs to be improved towards the $1\ns$ (see Figure~\ref{fig:}).

+% Beacon introduction %<<<
 A viable method to obtain this timing accuracy is to incorporate a beacon transmitter into the array.
-This (narrow-band) transmitter sends out a special\Todo{word} signal that is picked up by the radio antennas in the array.
-With relatively simple techniques, the timing accuracy can be improved to below $1\ns$ (see Figures~\ref{fig:},~\ref{fig:}).

 Thus, at a relatively low cost, the (relative) timing of radio arrays can be improved to enable radio interferometry.

+% Passive Beacon %<<<
 In some circumstances, an external transmitter can be used as a beacon.
-For example, in \gls{Auger}, a public TV broadcaster emits its signal at $f = 62.75\MHz$ from \Todo{name} (approximately $75\;\mathrm{km}$ north-west of the array\Todo{verify}).
-With the source location and the frequency known, time delays can be calculated and this signal can be used to remove\Todo{word} timing errors smaller than $T = 1/f \sim 16\ns$.
-Unfortunately, with the \gls{GNSS} timing accuracy estimated in the same order of magnitude and the signal being periodic, the synchronisation of the antennas can be off by an integer amount of periods $T$.\Todo{rewrite}

+% Combined sine beacon + air shower %<<<
 Recording an air shower, in addition to such a narrow-band beacon, might provide a method to determine the correct beacon period.
 Radio interferometeric analysis of the air shower depends on the coherence of the received signals.
-Any synchronicity problems in the radio antennas decrease the observed power of the reconstructed air shower.
-With a limited set of periods to try\Todo{word}, this power can be maximised \Todo{word} while simultaneously determining the correct beacon period.
+Any synchronicity problems in the radio antennas decrease the coherence and thus the power mapping used to derive properties of the air shower.
+With a limited set of periods to test, this power can be maximised while simultaneously inferring the correct beacon period.

+The developed method to synchronise can be directly tested at \gls{Auger}, both with data from \gls{AERA} and the upcoming radio detectors from AugerPrime.
