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.

Abstract: A system and method are provided for implementing system controlled randomization and related functioning in screening procedures when granting individuals entry into certain limited access areas. The disclosed schemes supplement personnel access systems with additional user aware features to implement standard objective randomization processes for the selection, identification and tracking of individuals for separate levels of screening. The randomization scheme is tracked to collect information regarding the selection of individuals from the group of all individuals screened at a particular screening checkpoint to verifiably prove objective randomness in the implementation of the randomization scheme. An additional verifiable capability is provided to modify the randomization scheme locally, or from a centralized location, to adapt to changing situations while maintaining the objectivity in the scheme.
