Explanation:

GPS and code - scanning technology are commonly used for tracking packages. GPS provides location information while code - scanning (like bar - code or QR - code scanning) records the package's movement at different checkpoints. Robotic arms are for loading, not tracking. A learning management system is for educational purposes, not package tracking.
