Abstract

An aircraft system comprises a first and second transceiver each configured to transmit and receive radio signals in respective first millimeter wave (mmW) frequency band and second mmW frequency band; and a processing unit configured to provide the data signals to the first and second transceivers for transmission and to receive demodulated signals from the first and second transceivers. The processing unit is further configured to output signals to alter the orientation of the first antenna to establish a first point-to-point connection with a first aircraft and to output signals to alter the orientation of the second antenna to establish a second point-to-point connection with a second aircraft; the first point-to-point connection and the second point-to-point connection forming part of a point-to-point aircraft relay ring network communicatively coupling a plurality of aircraft in a shared flight route area to each other.

Claims

1. A system configured to be installed on a first vehicle, the system comprising:

at least one transceiver configured to transmit and receive signals;

processing circuitry coupled to the at least one transceiver;

wherein the processing circuitry is configured to provide data signals to the at least one transceiver for transmission by the at least one transceiver and to receive demodulated signals from the at least one transceiver;

wherein the processing circuitry is further configured to output signals to alter orientation of at least a portion of the at least one transceiver to establish a point-to-point connection with a second vehicle;

wherein the processing circuitry is further configured to compare characteristics of signals, received from the second vehicle via the at least one transceiver, with a model relating signal characteristics to weather to determine weather conditions of an area through which the received signals passed; and

wherein the processing circuitry is further configured to modify, in response to the determined weather conditions, operation of the at least one transceiver.

2. The system of claim 1, wherein the at least one transceiver includes an antenna.

3. The system of claim 2, wherein modifying the operation of the at least one transceiver comprises modifying a beam of the antenna.

4. The system of claim 1, wherein modifying the operation of the at least one transceiver comprises modifying a modulation scheme used by the at least one transceiver.

5. The system of claim 1, wherein the at least one transceiver comprises at least one of a free space optical transceiver comprising a laser, and a millimeter-wave transceiver.

6. The system of claim 5, if the at least one transceiver comprises the free space optical transceiver comprising the laser, then the processing circuitry is configured to direct a beam of the laser away from vehicle crew.

7. The system of claim 1, wherein the processing circuitry is further configured to transmit weather data regarding the determined weather conditions to the second vehicle via the at least one transceiver.

8. The system of claim 1, further comprising an inertial management circuitry having at least one gyroscope and at least one accelerometer;

and

wherein the processing circuitry is further configured to use measurements from inertial management circuitry to determine the orientation of the at least the portion of the at least one transceiver to establish the point-to-point connection.

9. The system of claim 1, further comprising:

a second at least one transceiver, coupled to the processing circuitry, configured to transmit and receive signals;

wherein the processing system is configured to output signals to alter orientation of at least a portion of the second at least one transceiver to establish a second point-to-point connection with a third vehicle

wherein the processing circuitry is further configured to compare characteristics of signals, received from the third vehicle via the second at least one transceiver, with a model relating signal characteristics to weather to determine weather conditions of an area through which the received signals passed; and

wherein the processing circuitry is further configured to modify, in response to the determined weather conditions, operation of the second at least one transceiver.
