Lessons Learned - Cone Angle Anomaly in Canopus Star Tracke
Year: 1995
Abstract: Abstract:
An anomaly in the cone angle circuitry of the Voyager Canopus Star Tracker was probably due to a Delrin insulating sleeve decomposing after exposure to Jupiter radiation fields, causing a high resistance path through the Delrin. Ground metal shielding boxes and metal masses on circuit boards, analyze/test materials that could be exposed to ionizing radiation, and maintain spare hardware to enable failure analysis.
