Abstract

This project aimed to mitigate vibration-induced errors in Assured Positioning, Navigation, and Timing (APNT) devies, particularly in aerospace environments. The study explored the effectiveness of vibration damping materials, specifically Thermoplastic Polyurethane (TPU) and Memory Foam, in reducing the transmission of vibrations to an APNT replica. Experimental results showed that different material combinations provided for the most vibration reduction, with TPU at 10% infill and Memory Foam showing the best performance. Although the stacked material setup showed promising results, it was not ideal for real-worl aerospace applications due to practical constraints. Overall, this study provides valuable insights into improving the reliability of APNT devices in GPS-denied environments, contributing to the ongoing advancement of navigational technologies in demanding operational environments.
