Think over Trajectories: Leveraging Video Generation to Reconstruct GPS Trajectories from Cellular Signaling

arXiv:2603.26610v1 Announce Type: cross Abstract: Mobile devices continuously interact with cellular base stations, generating massive volumes of signaling records that provide broad coverage for understanding human mobility. However, such records offer only coarse location cues (e.g., serving-cell identifiers) and therefore limit their direct use in applications that require high-precision GPS trajectories. This paper studies the Sig2GPS problem: reconstructing GPS trajectories from cellular si
