Lessons Learned – Galileo Attitude Control Power on Reset Problem
Year: 1993
Abstract: Abstract:
A potentially catastrophic Power On Reset (POR) was discovered during testing of the Galileo orbiter. The problem was traced to noise from a capacitive coupling path between flight subsystem ground and support equipment ground. AC ground paths should be testable and should be verified in system interface verification tests. Interface circuits should be analyzed to identify any AC coupling paths between independent ground trees.
