Electronics Probabilistic/Prognostics, a Qualification Paradigm Shift with HITL

摘要

Communication and navigation technologies require significant improvement relative to the current robotic data rates, as reported in rigrous studies on journies to Mars. With human in the loop (HITL), restriction- using only space grade electronics for robotic's systems-may be relieved, but safety controls need to be added. Human resourcefulness enables tapping into commercial-off-the-shelf (COST) electronics systems -a paradigm shift - which requires new rigrous probablistic qualification approaches to be developed, including use of physics-of-failure and prognostic methods. New qualification methods intended to provide early warning indications, and allow timely replacement of the life-limited electronics COTS systems, are a viable option with HITL. At this time, the refurbishing option is impossible with robotics missions; the reason for a significant cost burden and schedule impact is due to ensuring the robustness of electronics systems that meetg the extremely harsh and long-life mission requirements. This paper presents packaging technologies and probablistic/prognostic approaches with reliability test results for both robust and COTS abundant electronic technologies.
