MicNest: Long-Range Instant Acoustic Localization of Drones for Precise Landing (Best Paper Runner‑Up at ACM SenSys 2023)

MicNest, the Best Paper Runner‑Up at ACM SenSys 2023, introduces a long‑range instant acoustic localization system that lets drones emit PRN‑modulated sound pulses captured by a four‑mic ground array to compute ToA/TDoA, achieving sub‑meter (0.5 %) accuracy up to 120 m in noisy urban settings and enabling precise, robust landing for Meituan’s delivery fleet.
