Range –based localization Bearing –base localization Uncertainty S. JOB Profile: Backend processing for Document & Distribution (D&D) Supporting Asia region as well as US Region. Localization schemes can be categorized into range-based (fine-grained) and range-free (coarse-grained). high-resolution laser scanners. Trilateration-Based Localization Algorithm Using the Lemoine Point Formulation Ming-Shih Huang and Ram M. RSSI (receive signal strength indicator) is the most common technique used for distance estimation.
