+In contrast to the earlier described hardware, nanoBTS, which the University of Freiburg
+already owned, the budget for the GPS receiver was limited and the Navilock NL-402U
+was bought considering only the single criterion, the price. The Navilock NL-402U
+GPS receiver is based on the u-blox UBX-G5000 single chipset and is a one
+chip solution \citep{ubxDatasheet}. It can be seen on Figure \ref{img:gpsNavilock}
+with its passive ceramic patch antenna. 1575,42 MHz is the operating frequency of
+the receiver which corresponds to the L1 civil frequencies and Coarse/Acquisition (C/A) code.
+The GPS chipset consists of 50 channels,
+each channel tracks the transmission from a single satellite \citep{understandGPS}.
+It is important to note, the number of channels inside a GPS receiver interrelates
+with the amount of time required to get the first fix. Receiver tracking sensitivity is
+-160 dBm ($10^{-16}$ mW).
+The GPS receiver communicates with the computer ovet the USB port.
+Although the GPS receiver uses an USB interface, on the computer it emulates 2 UART ports,
+which are serial communication interfaces.
