Abstract
A new method of real-time GPS/WAAS user positioning quality control for transportation applications is considered. Current quality of positioning is defined through the GPS/WAAS user's required navigation parameters (RNP) such as positioning accuracy and positioning availability taking in account the current Positioning Delusion of Precision (PDOP). The method is based on real-time assessment of the RNP achievement total probability for the concrete GPS/WAAS user within WAAS coverage zone. The method allows detecting sudden positioning quality deterioration for the concrete RNP of aviation users and can be effectively used for some transportation applications which have strong RNP. Especially, the method can be recommended for transportation applications such as aviation landing systems and automatic railroad traffic control.
