1. Work Package 1
The main objective of WP1 was to provide an assessment of current state of the art in ATC/ATM with particular focus on separation minima in non-radar airspace (NRA) as well as in space-based ADS-B out of which a summary of high-level requirements as the starting point and driver for the rest of the work packages of the SALSA project. For this purpose the beneficiaries involved have scrutinized the available publications and regulatory documents as well as analyzed current procedures in air traffic control centers.
WP1 was divided into three tasks:
• Task T1.1 focused on the ATC/ATM perspectives, the developments/issues relating to the separation minima in the non-radar airspace (NRA). It addressed related issues, constraints and on-going developments irrespective of the technologies.
• Task T1.2 focused on the current development of the space-based ADS-B (SB ADS_B). It assessed the industry development (e.g. Iridium) and in particular European development (e.g. PROBA V), highlighting the issues, benefits and aspirations of the industry.
• Task T1.3 focused on a high-level summary of User Requirements for multi-source ADS-B. T1.3 reflected the assessments made in T1.1 and T1.2 and provided a perspective of requirements from the end-users (such as ANSP).
With the submission of these documents and their final acceptance by SESAR JU work package 1 has been successfully concluded.
2. Work package 2
The objective of WP2 (Multi-Source ADS-B System Modelling) was to build on the WP1 results and to deliver a high-level reference architecture for a multi-source ADS-B System, and a simulation/models to study and validate the system to achieve new separation standards for potential use, with proven benefits.
WP2 was divided into five tasks:
• T2.1 is for developing an outline concept of architecture for Multi-source ADS-B Surveillance.
• T2.2 is independent analytical work, and provides models for generating and validating revised separation minima and airspace capacity.
• T2.3 is driven by T2.1 and T2.2 to ascertain the performance requirements for the SB ADS-B.
• T2.4 provides a Multi-source ADS-B data chain model, taking into consideration the data requirements for both spacebased and non-space based ADS-B.
• T2.5 is the consolidated summary of Multi-source ADS-B System/Performance study, reflecting the end-to-end performance requirements in alignment with the findings of T2.2 T2.3 and simulation of other sources of ADS-B data (vessel-based, air-based).
Work package 2 has been successfully concluded.
3. Work package 3
The main objective of WP 3 was to discuss preliminary design alternatives for a Space-based ADS-B system and assess the impacts of the introduction of new separation standards in the context of Multi-source ADS-B.
It comprises of two streams of work:
One stream relates to the impact assessment due to the introduction of new separation standards in the context of Multisource
ADS-B.
- T3.3 focuses on the procedural impact assessment for the revised separation standards.
- T3.4 is for the assessment of the impact of system performance on flight-safety.
The other stream relates to the preliminary design of SB ADS-B and high-level assessment to support the
recommendations for way-forward actions for the Multi-source ADS-B
- T3.1 focuses on space segment design and analysis
- T3.2 focuses on the ground segment
The activities in tasks T3.1 and T3.2 were able to support WP4 in drawing up the project conclusions and recommendations in a timely manner.
Work package 3 has been successfully concluded.
