The Aircraft Data Acquisition System (ADA) consists of several systems, the Nose Front End (ADA-N), the Radiation Front end (ADA-R) and the Central Front End (ADA-C). All units connect to different sensors from which they gather data and transfer it on request to a data server. For this they have high speed data communication implemented on a FPGA, as well as precise timing algorithms, for keeping the units in an accurate execution. A Web-GUI allows to view the application with a standard web browser. This GUI provides the user additional status information and allows to edit the configuration of the system. The systems are programmed with LabVIEW and installed on a National Instruments CompactRIO cRIO 9025 platform with several IO modules. All components are powered by 28 VDC. The Nose Front End is installed in the nose compartment of the aircraft while the other front ends are installed in racks. The Nose Front End communicates with the Central Front End via a permantently installed fibre optic cable.
