SALSA

Satellite-based Automatic-Dependent-Surveillance-Broadcast for Lower Separation Minima Application. 

Continuous surveillance using Multi-source ADS-B for Enhancing Separation Minima Standards

Funded by the Single European Sky ATM Research Joint Undertaking (SESAR JU), the 24-months study he project SALSA addresses an enhanced approach in the use of ADS-B surveillance data for managing the airspace separation minima requirements in the non-radar airspace by the fusion of multi-source ADS-B.

Status

Funded by the Single European Sky ATM Research Joint Undertaking (SESAR JU), the 24-months study he project SALSA addresses an enhanced approach in the use of ADS-B surveillance data for managing the airspace separation minima requirements in the non-radar airspace by the fusion of multi-source ADS-B. If the impact is confirmed, the concept will contribute to reduction in the airspace minima requirements and thus to a set of new separation minima standards for the non-radar airspace; it would also contribute to the enhanced concept of operations for the Air-Traffic-Control/Air-Traffic-Management (ATC/ATM) in the Non-Radar Airspace NRA similar to radar airspace (RA), as ADS-B surveillance is available through out all Phases of Flight (PoF).  The project SALSA explores Multi-Source ADS-B based on ADS-B surveillance from the ground, air and space based receiver technologies as well as the usefulness of ADS-B rebroadcast using maritime relays in the oceanic airspace . 

In Progress

  •          Progress Review 1 : successfully held at the Airbus Site in Immenstaad 12th October 2017
  •          Progress Review 2 : successfully held at the SESAR JU  in Belgium 29th March 2017
  •          Progress Review 3 : successfully hled at the DLR Site in Braunschweig 25th October 2017
  •          Final Review 4 : Planned to be held at the SESAR JU offices in Belgium in March 2018

Benefits

SALSA will bring positive impact to the prevailing ATC/ATM operations through the introduction of innovative concepts that could enhance the existing separation standards with increased surveillance capabilities in the non-radar airspace, benefiting directly to Air Navigation Service Providers (ANSP) and Air Operator (AO), and indirectly to other stakeholders such as Aviation Users (AU) and Network Managers (NM).

  •             Increased safety
  •             Increased efficiency
  •             Increased Capacity
  •             Enhanced operations
  •             Reduced emissions
  •             Reduced number of separation minima
  •             Promoting Competitive Advantages

News

SALSA is based on Multi-source ADS-B architecture of a system-of-systems that can automatically track, acquire and deliver trajectory information to ATC.  Starting with an assessment of prevailing state and current developments in the context area in ATC/ATM and the extension of Free Route Airspace (FRA) foreseen by SESAR, SALSA aims to present the revised separation minima as potential new standard for the non-radar airspace. SALSA aims to achieve such new standards based on exploratory research and robust simulation and modelling in the context of multi-source ADS-B system and required performances.  Although SALSA modelling and simulation are primarily for the separation minima reduction and not as a predictor of collision-risks, as part of the study, first assessment of impact of system performance on flight safety is provided.

The study outcome will provide a basis for further developing the concept for the intended benefits of multi-source ADS-B in supporting enhanced air-space and separation management.
