 	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.

 	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.
