Abstract

A system and method are provided for monitoring, collecting and aggregating position information from multiple independent data sources to localize a position of an aircraft operating worldwide. The localized position information is provided to one or more end-users or stakeholders in a format for direct integration into one or more mapping and/or situational awareness display applications. Information is collected from a plurality of monitored data sources. Weighted values are applied to certain of the information collected from the plurality of data sources according to known or predictable/determinable static and/or dynamic accuracy errors and latencies of the information provided. A detailed analytic algorithm is applied to provide a probabilistic analysis that results in a resolution of a real-time, or near real-time, aircraft location, as well as an ability to accurately predict an aircraft location along a track at some future time.
