Abstract

We present the results of the Pre-Phase A study of a subsystem and components onboard the LiteBIRD mission, whose scientific objective is to study the cosmic microwave background to search for the evidence of cosmic inflation in the very early universe. The study was conducted according to systems-engineering processes. We have a draft interface requirement document (IRD) for the subsystem from the system that is one layer higher in the LiteBIRD product tree. Taking it as the “stakeholder’s expectation,” we conducted the three process groups: the system-design, the product-realization, and the technical-management processes. In the processes, we found several issues in the IRD, and started discussing to mitigate them. The results were summarized in draft baseline documents which formed a part of the input package for the mission definition review held at JAXA in 2023-24.
