Objectives
The project consists of a product phase and a technology phase.
The product phase objective is the new Dialog® release 2.5.1 that offers the following new capabilities:
-
Support of Mx-DMA MRC return link technology with symbol rates up to 100 Mbaud
-
Support of mobility networks with 7k terminals roaming over 250 beams
-
Support of free-running/unslaved BUCs for MRC terminals
-
Hub and terminal access security
The technology phase has two research and prototype tracks. One track investigates the use of AI/ML for optimizing the ACM algorithm. The other track focuses on improving the capacity and related symbol rates of satellite networks using virtual carriers in a physical wideband carrier.
Challenges
One of the major challenges of the project is the improved scalability:
-
As the Dialog product is very complex, the initial assessment of the scalability bottlenecks could be wrong leading to wrong effort assumptions
-
The scalability requirement is simulated and tested in a lab environment and behaviour could be different in a real environment
Another technology challenge is the MCD7500 channelizer upgrade which could run into problems when increasing the symbol rate for MRC, causing FPGA resource issues.
System Architecture
The product is entirely built on the existing Dialog ® architecture.
Plan
The project has the following key milestones for the product and technology phase.
For the product phase, the key milestones are:
-
CDR, at which technical requirements, top-level architecture and design documents are approved. The CDR milestone is split in two parts: CDR part-1 concerns the MRC 100Mbaud capability, and CDR part-2 the Dialog R2.5.1.
-
TRR, at which the test strategy and facilities are ready
-
FAT & FR, at which the factory acceptance test and final review is completed to confirm readiness for product realisation
For the technology phase, the key milestones are:
-
PDR, at which the PoCs are approved
-
TRR, at which the research is ready for verification and validation
-
FR, at which the final review is completed to verify the new technology solutions in a system context
Current Status
The project kicked off on March 2022 and has achieved PDR and CDR part 1.
Work currently in progress.
