Localization Accuracy Model Incorporating Signal Detection Performance for Wide Area Multilateration.

Wide area multilateration (WAM) estimates aircraft positions on the basis of time difference of arrival (TDOA) for air traffic control. To design the receiver positions, dilution of precision has been used. However, the conventional approach ignores failure in signal detection. Therefore, this paper proposes a novel WAM accuracy model for more realistic performance prediction. The proposed model employs a stochastic constellation, i.e., the constellation of available receivers virtually changes according to the signal detection performance. [ABSTRACT FROM AUTHOR]
