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 both 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.
