Single Board Computer Based Data Acquisition System for Monitoring Parameters of Reusable Launch Vehicle Interface System

With the upcoming technology demonstration projects such as the Reusable Launch Vehicle, easily portable data acquisition systems for ground testing are the need of the hour. The existing data acquisition systems used in ISRO are generally larger and of higher capability based on the number parameters to be acquired, which makes them underutilized in this case. To avoid this problem, a data acquisition system based on BeagleBone^® Black, a Single Board Computer (SBC) is conceived. With this approach the number of components utilized would be reduced as we make use of ADCs present in the BeagleBone computer. Also, the size of the hardware setup is significantly reduced as the chosen SBC is small, making the developed Data Acquisition system portable. It could be moved anywhere with ease, even to the runway, where the final phase of ground testing happens.
