ADS-C Ground Distribution SWIM Service 1.0
Abstract
The ADS-C Ground Distribution Service distributes to ground users the ADS-C data collected from ATS B2 equipped aircraft by the ADS-C Common Service. It supports a Publish/Subscribe Push Message Exchange Pattern for the distribution of ADS-C data, flight status changes and Request/Reply Message Exchange Pattern to support the creation of Demand Contract Requests and to query flight status by ground users.
This service definition summarizes the service as defined in the full specification EUROCONTROL Specification for Data Link Ground Distribution SWIM Services. The specification should be considered the primary reference. Please consult it for complete and authoritative information.

Operational Needs
The demonstration of an ADS-C Common Service to collect and distribute ADS-C data from flights has been achieved by SESAR PJ38 (ADSCENSIO). The SESAR PJ38 deliverable identified operational needs and benefits of such an ADS-C Common Service.
The SWIM ADS-C Ground Distribution Service shall be implemented over a Technical Infrastructure conformant with the SWIM-TI Yellow Profile (v1.1+) Infrastructure Capabilities Specification. Conformance with the SWIM-TI Yellow Profile Infrastructure Capabilities Specification is achieved by satisfying the requirements of the Infrastructure Capabilities of the SWIM-TI Yellow Profile (v1.1+)
Capabilities
The ADS-C Ground Distribution Service enables a number of operational use cases that are described in the EUROCONTROL Specification for Data Link Ground Distribution SWIM Services: Subscribe to ADS-C Messages by Specific ICAO 24-bit Aircraft Addresses. Subscribe to ADS-C Messages matching a Filter Condition. Receive Messages from Predefined Subscriptions. Enables consumer to perform a Demand Contract Request. Enables a consumer to query Flight Status details about a flight. ADS-C Ground Distribution Service Status Monitoring.

The Flight Status Data Publication Interface allows a consumer to obtain updates of the ADS-C exchanges of the flights he is interested in. It provides two ways of doing so: By creating an endpoint from which a consumer can listen to updates of flights matching certain filtering criteria defined in a subscription created through the Flight Status Subscription Management Interface. In which case he will receive in its subscription response the endpoint address created specifically for his subscription. The dynamic endpoint created for a specific subscription is labelled by /<address> in this document, the specific value taken by the <address> placeholder is resolved in runtime and provided in the subscription response. By defining a number of preconfigured static endpoints where predefined filters are already applied. These preconfigured static endpoints do not require the creation of a specific subscription by the consumer, they are created in design-time by the service provider and are readily available for any consumer, subject to authorization verification. These static endpoints are labelled by /<predefinedSubscription> in this document, the specific values taken by these endpoints is defined by the service provider during design-time.

Aircraft can provide essential information to support accurate and reliable trajectory prediction or alternative scenarios during the execution of a flight. The EU-funded PJ38-W3-ADSCENSIO project will improve several characteristics of air traffic control through the better prediction of flightsâ behaviour. The project demonstrated the improvements in several operations performed by air traffic controllers as well as the efficiency and strength of a technological infrastructure to support the data link communications between the aircraft and ground on trajectory-related exchanges. The adoption of technical and operational solutions reduced controller workload in high traffic conditions, increase airspace capacity, and reduce flight delays, fuel consumption and CO2 emissions. https://cordis.europa.eu/project/id/101017626/results 27/06/23

The Advanced Message Queuing Protocol (AMQP) is an open internet protocol for business messaging. It defines a binary wire-level protocol that allows for the reliable exchange of business messages between two parties. AMQP has a layered architecture and the specification is organized as a set of parts that reflects that architecture. Part 1 defines the AMQP type system and encoding. Part 2 defines the AMQP transport layer, an efficient, binary, peer-to-peer protocol for transporting messages between two processes over a network. Part 3 defines the AMQP message format, with a concrete encoding. Part 4 defines how interactions can be grouped within atomic transactions. Part 5 defines the AMQP security layers. https://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-messaging-v1.0-… 10/12

The Single European Skys ATM Research project, SESAR, is one of the most ambitious modernisation projects launched by the European Union, contributing to the implementation of the Single European Sky. SESARs goal is to define, develop and deploy the technological solutions needed to increase the performance and digitalisation of Europes ATM system in the most cost-, flight-efficient and environmentally friendly conditions. The adoption of the Reg. (EU) n. 716/2014 (Pilot Common Project or PCP), the establishment of the SESAR Deployment Manager as per Reg. (EU) n. 409/2013, as well as the subsequent elaboration of the initial SESAR Deployment Programme, marked all together a key step towards the Deployment Phase of SESAR. https://www.sesardeploymentmanager.eu/news/common-project-1-a-new-europ… 02/02/2021
