+	Radio Detectors have been succesfully applied for detecting airshowers, which are caused by a cosmic ray impinging on the Earth's atmosphere.
+	In such an airshower, successive interactions will create charged particles which in turn cause a specific electromagnetic signal.
+	Measuring the development over time of such a signal will give a better insight in the energy content of the shower, and, in turn, allow for better resolution of the initial cosmic ray's properties.
+\\
+
+	A difficulty for radio detectors is that, because of their extent, the stations need to communicate wirelessly.
+	But an accurate timing is needed to follow this signal.
+	Advanced analyses require a timing accuracy on the order of $1$~nanosecond, while current detectors reach a timing accuracy up to around $10$-nanoseconds.
+\\
+
+	Various mechanisms are employed to increase the timing accuracy, overall and per station.
+	Since radio detectors only have a horizontal extent, keeping to horizontal showers allows for using the spatial distance as an additional timing mechanism.
+
+	Another important mechanism involves GPS chips.
+	Such a chip tracks satellites around the Earth.
+	These satellites sent out signals which can be used to triangulate the position (and time) of the chip.
+
+	Beacons are another example.
+	Sending out a specific signal allows to track this signal across individual stations.
+	By introducing characteristics into the signal such as beating, the stations then have a time calibration system setup.
+\\
+
+	This internship concerns itself with increasing the timing accuracy by investigating the various mechanisms (and their issues) used as timing calibration.
+
+	For example, since the spatial extent of the radio detectors is large, it might happen that a station on one side might track more or different satellites than a station on the other side of the detector.
+	This might introduce a timing difference for GPS chips, decreasing the total timing accuracy attained by the detector.
