Abstract

An integrated, externally-mounted Automated Dependent Surveillance-Broadcast (ADS-B) device comprising in one embodiment a 1030 MHz transmitter, a 1030 MHz antenna, a 1090 MHz receiver, a 1090 MHz antenna, a GNSS receiver, at least one GNSS antenna, a 978 MHz transmitter, and a 978 MHz antenna, wherein these components are integrated into a single enclosure, and wherein the GNSS antenna is placed at least partially into a projection extending out from the main enclosure body, such that the GNSS antenna has improved visibility to GNSS signals originating from altitudes above the current altitude of aircraft when the ADS-B device is mounted on the bottom of an aircraft.

Claims

1. An ADS-B device, comprising:

a 1030 MHz transmitter;

a 1030 MHz antenna;

a 1090 MHz receiver;

a 1090 MHz antenna;

a GNSS receiver;

a pair of GNSS antennae each connected to said GNSS receiver;

a 978 MHz transmitter;

a 978 MHz antenna;

an enclosure comprising a main enclosure body and a pair of winglets each mounted on and extending laterally from a respective side of said main enclosure body; and

wherein the 1030 MHz transmitter, the 1030 MHz antenna, the 1090 MHz receiver, the 1090 MHz antenna, the GNSS receiver, the GNSS antennae, the 978 MHz transmitter, and the 978 MHz antenna are contained within the enclosure, wherein each said GNSS antenna is placed in a respective winglet, wherein the enclosure is mounted to the underside of the exterior of an aircraft, wherein each said winglet extends laterally out from the main enclosure body such that the GNSS antannae have improved visibility to GNSS signals originating from altitudes above the current altitude of aircraft, wherein the 1090 MHz receiver receives data transmitted by an external 1090 MHz transponder for use in preparing an ADS-B broadcast, and wherein the 1030 MHz transmitter may be used to request a transmission of data from the external 1090 MHz transponder.

2. The ADS-B device of claim 1, wherein the 1030 MHz antenna, the 1090 MHz antenna, and the 978 MHz antenna are the same antenna.

3. The ADS-B device of claim 1, wherein said projections are flexible and are each adhered to a respective side of the exterior of the aircraft fuselage.

4. The ADS-B device of claim 1 wherein said enclosure includes:

a main enclosure body depending downwardly from the underside of the aircraft fuselage terminating at a lower end; and

said winglets extending laterally outwardly from said main enclosure body lower end.

5. The ADS-B device of claim 1 wherein each said winglet has an upwardly-concave curved configuration and is mounted flush against a respective aircraft fuselage side.

6. An ADS-B device, comprising

a 1090 MHz receiver;

a 1090 MHz antenna;

a GNSS receiver;

a pair of GNSS antennae each connected to said GNSS receiver;

a 978 MHz transmitter;

a 978 MHz antenna;

an enclosure comprising a main enclosure body and a pair of winglets each mounted on and extending laterally from a respective side of said main enclosure body; and

wherein the 1090 MHz receiver, the 1090 MHz antenna, the GNSS receiver, the GNSS antennae, the 978 MHz transmitter, and the 978 MHz antenna are contained within the enclosure, wherein each said GNSS antenna is placed in a respective winglet, wherein the enclosure is mounted to the underside of the exterior of an aircraft, wherein each said winglet extends laterally out from the main enclosure body such that the GNSS antannae have improved visibility to GNSS signals originating from altitudes above the current altitude of aircraft, and wherein the 1090 MHz receiver receives data transmitted incidentally by an external 1090 MHz transponder for use in preparing an ADS-B broadcast.

7. The ADS-B device of claim 6, wherein the 1090 MHz antenna and the 978 MHz antenna are the same antenna.

8. The ADS-B device of claim 6, wherein said projections are flexible and are each adhered to a respective side of the exterior of the aircraft fuselage.

9. The ADS-B device of claim 6 wherein said enclosure includes:

a main enclosure body depending downwardly from the underside of the aircraft fuselage terminating at a lower end; and

said winglets extending laterally outwardly from said main enclosure body lower end.

10. The ADS-B device of claim 6 wherein each said winglet has an upwardly-concave curved configuration and is mounted flush against a respective aircraft fuselage side.
