Abstract
In a first, preferred embodiment of the present invention, integrated tracking is provided using passive broadband. The invention takes the system for deployable passive broadband detection and extends it by incorporating the capability to decode position for ADS-B, SSR multilateration, and broadband multilateration. In a second embodiment, validation of a self-reported position is provided. The invention takes the system for deployable passive broadband detection and extends it by incorporating the capability to decode self-reported position for ADS-B, and compare it to line of calculated position, or line of precision, derived from multilateration techniques applied to various signals received from the aircraft. In a third embodiment, validation of a self-reported ADS-B position using independent surveillance is provided by the system.
