Device and Service for transfer of telemetry data between airport and ground: IP.COM

Abstract

The present proposal comprises of two or more servers, of which at least one is located on an aircraft and another is located on ground.

The aircraft segment server on the fuselage has means to communicate with other aircraft located equipment like sensors, actors or entire computer networks. Furthermore does the airborne server consist of memory and means to communicate to the ground segment.

The ground segment provides a similar function for all ground located clients. Essential is the bi-directional communication between the two server segments. This communication may utilize different routes, e.g. via L-Band satellite, Ku/Ka-Band satellite, Gate connectivity or any air-to-ground radio communication. Independent of the selected data path the two segments ensure appropriate security and message integrity.

At the airborne/ground segment the server provides logins to its clients (necessary to ensure security / integrity). During Login the Client informs the server about its absent state (so called "testament"). While logged in, the server will stay connected and receive data at the client's discretion. Any set of data is provided with a label as an identifier, which is attributed to the data. The data set could be a single Boolean state, a variable, set of variables or even an entire file of any size. The server will store at least the latest instance of any data identifier. After successful reception the server publishes the data set to all affected subscribers.

At the ground/airbourne segment the server provides again a login to its clients. Any connected client can now subscribe to a data identifier and will immediately receive a message with the present status AND another message any time the data set is modified. During the subscription process the server checks the legitimacy of the request from the requestor.

Device and Service for transfer of telemetry data between airport and ground Technical background Middleware service providing a simple message queuing broker for all type of digital data sources or clients locally on the aircraft. A second broker (server) is available on ground. This way a transparent and secured transport of data from/to internet-of-things items to the ground is provided by the messaging service operator. Prior Art Proprietary services custom to applications. Similar MQTT / CoAP servers are widely used in the Internet of things. These servers do however not include the transport from air-to ground.

During the subscription process the server checks the legitimacy of the request from the requestor. The data identifier or subscription can be associated with an appropriate Quality of Service. The messaging system does not need to understand the data transmitted, it can be encrypted between sender and receiving subscriber.

Advantage:

• The Airbourne/Ground Segment messaging operator can offer a data agnostic link with appropriate QoS.

• The messaging service operator can ensure...
