N2 - Cooperative localization is one of the effective methods to restrain multipath fading and shadow fading in the urban environment whose positioning accuracy mainly depends on the ranging precision and the positioning effect of unmanned aerial vehicles(UAVs). Distance estimation including time of arrival(TOA) and received signal strength(RSS) whose accuracy is influenced significantly by the ranging model especially in antenna direction and random error modeling. In this paper, firstly, the improved TOA and RSS ranging model containing compensation of antenna direction is given by the static fitting experiment. Furthermore, the random error of TOA and RSS ranging is modeled as logarithmic function and polynomial function separately. Finally, the weighted least-squares method is proposed to verify the effectiveness of the improved model.
