Deployable passive broadband aircraft tracking
First Claim
1. A system for validating aircraft self-reported position, comprising:
- a plurality of antennas for receiving radio signals from an aircraft, including an aircraft self-reported position;
a processor, coupled to the plurality of antennas, for determining aircraft position through time difference of arrival processing of the signals from the aircraft to produce a determined aircraft position; and
a comparator, coupled to the processor, for comparing the determined aircraft position with the aircraft self-reported position and determining whether the self-reported position is within a predetermined range of the determined position.

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.
