Abstract:
Noise, deviations, and outliers with varying distribution characteristics exist in measured data for outdoor location estimation, propagation characteristics that make source location estimation difficult. The estimation error of conventional methods (typically a least-squares method) is increased by such outliers. To solve this problem, this study proposes a novel location estimation method, specifically a modified trilateration technique based on Apollonian circles that does not require knowing the exact transmission power of the source or carrying out a calibration procedure. The proposed method results in improved location estimates compared to existing methods, which is confirmed with robust filtering in verification experiments.
