Empirical Analysis of TOA and AOA in Hybrid Location Positioning Techniques

Abstract

We explored the role of TOA and AOA in hybrid positioning algorithms in the LOS environment, as well as the effects of weight parameters. We built a model to simulate the experimental process. The simulation environment is an environment of a multi-base station single mobile terminal built on a cellular network. We observed the change of the positioning error by changing the weight of the base station TOA and AOA, so as to analyze the influence of the weight parameter on the accuracy. The final simulation results show that AOA has little effect on the positioning algorithm in LOS communication, and the positioning algorithm mainly depends on TOA. The results of others do not indicate the role of weight parameters in the positioning algorithm, and our research makes up for this vacancy.
