Objectives
The project activity consists of developing a laboratory test-bed capable of emulating in real time a complete satcom system. The system implements the DVB-RCS mobile specifications, applicable to both LOS and NLOS conditions and for both aggregate and not-aggregate type of traffic. The targeted scenarios are the aeronautical, maritime and land-based (railway and vehicular) ones.
The test-bed will include a base-band terminal HW-emulator supporting mechanisms and functionalities from physical to MAC and Network layers, as described within the DVB-RCS mobile specifications. In particular, the terminal will be general enough to validate all the DVB-RCS mobility features in all the target scenarios.
A realistic hardware channel emulator for both the forward and return links will be developed and integrated within the test-bed. The channel emulator will be used within this project to consolidate DVB-RCS mobile technology and to verify the system performances in the relevant scenarios.
Scope of the project is also to provide stand-alone modules (same design of the test-bed) to upgrade the CTB used for SatLabs Terminals Certification.
Moreover, relevant system performances, outcome of this project, will be used within the DVB-RCS Mobile standardization activity as valuable input to complement the implementation guidelines work.
Challenges
This project is intended to perform:
- assessment of DVB-S2 system architecture and layers for mobile application;
- assessment of DVB-RCS system architecture and layers for mobile application;
- development of critical items with a clear commercial finalization;
- development of a Test Bed to have a realistic test environment;
- campaign of system-level validation tests.
Plan
The project is divided in two phases.
- The first phase aims to reassess the requirements and to consolidate the system specifications, with the support of analyses and simulations.
- The second phase includes a Management Task and five Technical Tasks concerns the equipment development:
– The first task cares for the architectural design;
– The second one for the detailed design;
– The third one for the definition of the test and validation Plan
– The Fourth one with hardware integration and conformance testing;
– Last technical Task is dedicated to the system-level validation and the interoperability tests.
The tasks are subdivided into a total of 46 Work Packages.
The WP responsibility is demanded to 11 highly qualified Key Persons
The project duration is 18 months and is organized as follows:
- an initial six-month period (Phase 1) in which the theoretical and computer simulation activities are carried out, with the aim to identify the best algorithms and implementation solutions, and hence consolidate the specifications;
- a eight-month period covering the design, implementation, integration, and functional verification of the specified equipment;
- a two-month period covering the system integration;
- a final two-month period for the system validation tests.
