Abstract: A method and apparatus for tracking the position of an aircraft. A tracking device comprises a satellite navigation system receiver, a satellite communications transceiver, and a processor hermetically sealed within a housing attached on an outside of the aircraft. The satellite navigation system receiver is used to identify the position of the aircraft using navigation signals received from a satellite navigation system. The processor generates position information identifying the position of the aircraft as identified using the navigation system receiver. The processor sends the position information to a receiving station via a communications satellite in a low Earth orbit using the satellite communications transceiver. The position information is automatically generated by the processor and sent to the receiving station at a desired rate.

Abstract: Systems, methods and computer-readable media are disclosed for generating integrated data records by correlating source data records stored at different registry source data repositories. A set of source data records is retrieved based on execution of one or more search queries against a set of registry source data repositories. A data record matching rule is selected for execution on the set of source data records. The matching rule specifies one or more input properties, each of which specifies at least one data field designator, and optionally, a matching algorithm and an input property match threshold value. The matching rule is executed on pairwise combinations of source data records to obtain a set of matched source data records. An integrated data record is generated and populated with respective data from each of one or more of the matched source data records. The integrated data record is linked to each source record.
