               <li>Developed a Jupyter Notebook-based tool to analyze telemetry packets from L0 satellite products, focusing on the detection of missing or anomalous packets. The tool aids in identifying unusual patterns and behaviors in specific products. Integrated the solution with the tm-packet-analyser utility to extract detailed packet-level information for in-depth analysis.</li>
