Abstract

A method and apparatus for providing distributed fleet communications between aircraft including decentralized location tracking, weather data, and fleet health is used to determine actual aircraft position, better weather data from multiple sources, and health data to help with logistical calculations and increase efficiencies. The communication is a distributed communication network using blockchains wherein the block includes a data, a hash and a prior hash, determining, by a processor, a validity of the block in response to a blockchain register stored on a memory, the hash and the prior hash, determining, by the processor. The processor is configured to generate a record to be added to the local copy of the blockchain ledger stored in the memory, then send an update to the fleet blockchain to be added as a valid record to be stored and used by the fleet or other trusted individual operators.

First claim

What is claimed is:

1 . A blockchain enabled aircraft secure communications system comprising:
a transceiver configured for receiving a block from an originating aircraft wherein the block includes a data, a hash and a prior hash; a memory configured for storing a blockchain register and an airspace map; a processor configured for determining a validity of the block in response to the blockchain register, the hash and the prior hash, determining a consistency of the data in response to the airspace map, determining a network consensus of the validity of the block, the processor being further operative to generate an updated blockchain register and an updated airspace map in response to the validity of the block, the network consensus and the consistency of the data; and a controller configured for controlling the aircraft in response to the updated airspace map.

2 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the block is rejected in response to determining an invalidity of the block.

3 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the consensus is determined by a trusted node in response to a plurality of distributed fleet network nodes.

4 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the data includes a velocity, an altitude, and a location of the originating aircraft.

5 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the data includes an environmental condition measured by the originating aircraft.

6 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the transceiver is further configured to transmit the validity of the block to a plurality of distributed fleet network nodes.

7 . The blockchain enabled aircraft secure communications system of claim 1 , wherein consensus is determined in response to a plurality of validity determinations received from a plurality of distributed fleet network nodes.

8 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the transceiver is further configured to transmit a notification of an inconsistency of the data to the originating aircraft.

9 . The blockchain enabled aircraft secure communications system of claim 1 , wherein the transceiver is further configured to transmit a notification of an inconsistency of the data to a plurality of distributed fleet network nodes.

10 . A method of transmitting data comprising:
receiving, by a transceiver, a block from an originating aircraft wherein the block includes a data, a hash and a prior hash; determining, by a processor, a validity of the block in response to a blockchain register stored on a memory, the hash and the prior hash; determining, by the processor, a consistency of the data in response to an airspace map stored on the memory; determining, by the processor, a network consensus of the validity of the block; generating, by the processor, an updated blockchain register and an updated airspace map in response to the validity of the block, the network consensus and the consistency of the data; and controlling, by an aircraft controller, a host aircraft in response to the updated airspace map.

11 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the block is rejected in response to determining an inconsistency of the block.

12 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the consensus is determined by a ground node in response to a plurality of distributed fleet network nodes.

13 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the data includes a velocity, an altitude, and a location of the originating aircraft.

14 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the data includes an environmental condition measured by the originating aircraft.

15 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the transceiver is further configured to transmit the validity of the block to a plurality of distributed fleet network nodes.

16 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein consensus is determined in response to a plurality of validity determinations received from a plurality of distributed fleet network nodes.

17 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the transceiver is further configured to transmit a notification of an inconsistency of the data to the originating aircraft.

18 . The method of transmitting data between an originating aircraft and a host aircraft of claim 10 , wherein the transceiver is further configured to transmit a notification of an inconsistency of the data to a plurality of distributed fleet network nodes.

19 . A distributed fleet communications method comprising:
receiving a block from an originating aircraft include a data, a hash and a prior hash, wherein the data includes a position of the originating aircraft; validating the block in response to the prior hash and a blockchain register; determining an inconsistency between the position of the originating aircraft and a prior position of the originating aircraft; rejecting the block; and transmitting an indication of the inconsistency to the originating aircraft.

20 . The distributed fleet communications method of claim 19 , including determining a current location of the originating aircraft and wherein the indication of the inconsistency of the originating aircraft includes the current location of the originating aircraft.
