Abstract

A system for air-ground (120) and air-air (122) communications wherein a VHF data radio (204) is coupled to a high-speed bus (304). The VHF data radio complies with the ARINC 716/750 standard and is accessible via the bus using a programmable interface (306). A communications management unit (208) can also be coupled to the high-speed bus, which communicates with the VHF data radio via the bus according to the programmable interface.

Claims

1. A system for air-ground and air-air communications, comprising:

a high-speed bus, said high-speed bus transmitting data signals at a speed greater than data signals are transmitted by an ARINC 429 protocol; and

a VHF data radio (VDR), coupled to said high-speed bus, wherein said VDR complies with the Aeronautical Radio, Inc. (ARINC) 716/750 standard and is accessible via said high-speed bus using a programmable interface.

2. The system of claim 1, further comprising a communications management unit (CMU) coupled to said high-speed bus.

3. The system of claim 1, wherein said high-speed bus comprises a PCI bus.

4. The system of claim 2, wherein said CMU complies with the ARINC 758 standard.

5. The system of claim 2, wherein said VDR and said CMU are housed with a single enclosure.

6. The system of claim 1, wherein said programmable interface comprises one or more message formats and one or more message protocols.

7. The system of claim 1, further comprising an antenna aperture coupled to said VDR.

8. The system of claim 2, wherein said CMU comprises:

a central processing unit (CPU) and input/output (I/O) card coupled to said high-speed bus; and

an ARINC I/O card coupled to said high-speed bus.

9. The system of claim 7, wherein said VDR comprises:

a power supply/power amplifier (PS/PA) card coupled to said high-speed bus; and

a receiver/demodulator, modulator/exciter, and digital signal processing (DSP) card coupled to said high-speed bus, to said PS/PA card, and to said antenna aperture.

10. The system of claim 1, wherein the programmable interface is defined in software within the VDR so as to allow the VDR to communicate with the high-speed bus.

11. A system for air-ground and air-air communications, comprising:

a high-speed internal bus, said high-speed bus transmitting data signals at a speed greater than data signals are transmitted by an ARINC 429 protocol;

a CMU coupled to said internal bus; and

a VDR, coupled to said internal bus, wherein said VDR complies with the ARINC 716/750 standard and communicates with said CMU via said internal bus using a VDR programmable interface.

12. The system of claim 11, wherein the VDR programmable interface provides various message formats and protocols that allow the VDR to communicate with the internal bus.

13. The system of claim 11, wherein the VDR programmable interface is defined in software within the VDR so as to allow the VDR to communicate with the internal bus.

14. The system of claim 11 further comprising a CMU programmable interface that allows the CMU to communicate with the internal bus.

15. The system of claim 14, wherein the CMU programmable interface is defined in software within the CMU.

16. A system for air-ground and air-air communications, said system comprising:

a high-speed bus;

an antenna aperture; and

a VHF data radio (VDR) coupled to the high-speed bus, said VDR including a power supply/power amplifier (PS/PA) card coupled to the high-speed bus and a receiver/demodulator, modulator/exciter and digital signal processing (DSP) card coupled to the high-speed bus, the PSA/PA card and the antenna aperture, wherein the VDR complies with the Aeronautical Radio, Inc. (ARINC) 716/750 standard and is accessible via the high-speed bus using a programmable interface.

17. The system of claim 16, further comprising a communications management unit (CMU) coupled to said high-speed bus.

18. The system of claim 17, wherein said CMU complies with the ARINC 758 standard.

19. The system of claim 17, wherein said CMU includes:

a central processing unit (CPU) and input/output (I/O) card coupled to said high-speed bus; and

an ARINC I/O card coupled to said high-speed bus.

20. The system of claim 16, wherein said high-speed bus includes a PCI bus.
