For example, various transponders and surveillance systems may benefit from reception methods that can distinguish between overlapping pulses from multiple sources. A method can include receiving, at an antenna, a first series of pulses from a first source. The method can also include receiving, at the antenna, a second series of pulses from a second source. The first series and the second series can at least partially overlap each other. The method can further include de-interleaving the first series from the second series using at least one non-time-domain technique.Type: GrantFiled: August 15, 2018Date of Patent: October 26, 2021Assignee: AVIATION COMMUNICATION & SURVEILLANCE SYSTEMS, LLCInventors: Robert John McCullen, Benjamin Jeffrey Paulson, Mark Dean Smith, James R.

Patent number: 10403159Abstract: There is provided an avionics system that provides several avionics functions within a single LRU. In one embodiment, the system comprises a software-configurable RF assembly, one or more processor assemblies that are configured to provide multiple TAWS/TCAS/Mode S/ADS-B/ATC functions, interfaces to allow connections to aircraft electronics and data loaders, and multipurpose antennas. In one embodiment, a common processor architecture allows generic avionics processors to be configured to operate a number of TAWS/TCAS/Mode S/ADS-B/ATC functions without the need for multiple LRUs, and software-defined RF functions allow RF circuitry that interfaces to the processors to handle current and future communication needs.Type: GrantFiled: June 30, 2014Date of Patent: September 3, 2019Assignee: AVIATION COMMUNICATION & SURVEILLANCE SYSTEMS LLCInventors: Cyro A.

Patent number: 10338210Abstract: Systems and methods can provide alternatives to a global positioning system (GPS). For example, certain systems can operate on 1090 MHz and provide for methods of estimating location that can be used in place of GPS. Thus, a method can include obtaining an estimate of position of an own aircraft based on time of arrival of signals from a plurality of ground stations. The calculation of the estimate can be performed in the own aircraft. The method can also include using the estimate of position instead of a position from a global positioning system.Type: GrantFiled: September 29, 2011Date of Patent: July 2, 2019Assignee: AVIATION COMMUNICATION & SURVEILLANCE SYSTEMS LLCInventors: Gregory T.

Patent number: 10324178Abstract: An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft, and the transmitted transponder Squawk code is received by a device positioned onboard the aircraft in which the transponder is installed. The ADS-B system is updated with the received transmitter squawk code. The squawk code is transmitted using the ADS-B system.Type: GrantFiled: December 22, 2015Date of Patent: June 18, 2019Assignee: L3 AVIATION PRODUCTS, INC.Inventors: Gary S. Watson, Lee R.

The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft and the transmitted transponder Squawk code with a device positioned onboard the aircraft. A Squawk code input of an ADS-B Squawk code to be transmitted with the ADS-B system is received. The ADS-B Squawk code is compared with the received transmitter Squawk code using a comparator and the pilot is informed whether the transmitter Squawk code matches the ADS-B Squawk code. A message formatter generates a message that includes the ADS-B Squawk code. A wireless transmitter broadcasts the ADS-B Squawk code generated by the message formatter.Type: GrantFiled: May 13, 2013Date of Patent: February 2, 2016Assignee: L-3 Communications Avionics Systems, Inc.Inventors: Gary S.

Publication number: 20100014615Abstract: Embodiments of the present invention provide for an overall hardware and software approach to Mode-S demodulation, especially where the Mode-S signals (such as squitters) have been modulated with multiple modulation protocols. Various implementations utilize coherent phase detection, since coherently detecting phase transitions in a multiple modulated signal results in better sensitivity and improved interference rejection over non-coherent modulation techniques. Further, addressing the demodulation of multiply-modulated signals may also be approached in embodiments of the present invention as a unified demodulation system, rather than disjoint demodulation of the separately modulated protocols.Type: ApplicationFiled: June 8, 2009Publication date: January 21, 2010Inventors: Gregory H.
