The Final Review has been performed.
The main outcome of the SAMARA project was the preliminary definition of a satellite-based communication system specifically designed for the provisioning over the ECAC area of satellite based ATS (Air Traffic Service) and AOC (Airline Operational Communication) Air Traffic Communication services between the airspace users and the ground aeronautical entities (ANSPs and Airline Operation Centers) aligned with the SESAR implementation of the Single European Sky target concept.
The satellite system trade-offs performed during SAMARA study indicate that, in order to comply with the aeronautical safety requirements, the space segment shall be composed by at least two geostationary telecommunications satellites as baseline to ensure the ATS/AOC services coverage to the ECAC area.
The two GEOs satellites shall operate in hot redundancy and shall support simultaneously the same coverage area with the same services.
Each satellite will provide the following mission services:
- L band Mobile link: Communication links between satellite and aircraft (uplink and downlink),
- Ku band Fixed link: Communication links between satellite and ground stations (uplink and downlink)
The SAMARA Consortium proposed a space segment deployment strategy which consists in delivering a subset satellite system with reduced capacity with respect to the operational system. The subset will be used to qualify the services and validate the system and to be used as space segment element for the full operational capability.
The proposed subset based on a small platform has been conceived to reduce the financial effort and make viable and affordable the SAMARA Business Case.
The SAMARA deployment strategy, fully aligned with the SESAR Master Plan, considers the following deployment sequence:
- 2014: launch of a Subset Payload,
- 2020: launch of the Full Operational Capability Satellite.
Starting from the Service Provision Model, identified for a centralized and a distributed ground segment scenario, all the costs for the SAMARA Satellite system have been derived.
The SAMARA Study has been completed with a Business Case performing a financial analysis evaluating the SAMARA System economic viability and the stakeholders risk sharing. Following the analysis, the SAMARA Business Case evaluated a cost-to-benefit ratio between 1.3 and 1.9 that indicates commercial attractiveness for securing long-term sustainability of the system for the final Iris System owner and service providers.
