Since the last eNews submission the SDP has successfully submitted and certified its last milestone, M19, and now is busy preparing for the next milestone, M20, Pre-CDR. The M20 Release Readiness Notice (RRN) was submitted in early March and contains 19 documents within the submission pack. This list includes Systems Engineering documents, Interface documentation (ICDs) and an updated snapshot of the latest SDP Architecture views since the M19 submission.
This pre-CDR milestone is a stepping stone to a successful CDR delivery in October. An incremental submission allows valuable key stakeholder feedback to be gained in particular on the architectural design to ensure continuous improvement and alignment of architectural priorities.
In addition to the finalisation of deliverables for Pre-CDR submission, other areas of focus for the Consortium are - further iterations of the SDP software architecture, advances in the SEI views of the high-level SDP architecture, continued understanding of the SDP interfaces, progress on the SDP functional model using the Algorithmic Reference Library (ARL), progress on the SDP prototyping testbed (P3) in Cambridge, progress on the SDP Integration Prototype (SIP) including end-to-end testing, consolidation of data models work, monitoring of the hardware costs evolution and updates to the corresponding predicted cost to name a few!
The sections below expand in further detail the recent work efforts and progress in the areas of platform and systems integration prototyping (P3, SIP) as well as the ARL. This work reduces risk and provides the rationale for design choices ahead of System CDR.
The next significant milestone for the SDP Consortium is M19 on the 30th November. M19 is a lightweight review of the current state of the SDP software architecture and forms a checkpoint with the SKAO to present the current state of the architecture and progress towards Critical Design Review (CDR).
All relevant SDP SEI style views and other supporting documentation for functionally close blocks of architecture will be reviewed. The goal is to present the information in sufficient detail to facilitate immediate use by a knowledgeable audience member.
In preparation for this review, a Stakeholders Overview will take place. The required participants will include key members of the SDP architectural design team and knowledgeable stakeholders from SKAO. This review is to ensure that the high-level architecture documentation, for the purposes of providing an introductory, high-level explanation of the design, is sufficiently complete. In preparation for this overview, key members of the SDP Architecture design team recently selected a collection of views for review and this information has been distributed to the SKAO.
Comments and or suggestions made during the Stakeholder Overview and the official M19 review will guide further architectural priorities ahead of M20 (Element pre-CDR).
