Abstract A Globalstar 2nd generation satellite experienced a reaction wheel mechanical failure, and in response Globalstar has been closely monitoring reaction wheel bearing friction. To prevent another reaction wheel hardware failure and subsequent shortened satellite mission life, a friction data processing methodology was developed as an on-orbit monitoring tool for the ground to issue early warning and take appropriate action on any hardware degradation or potential failure. The methodology, reaction wheel friction behavior, and its application to an on-orbit anomaly experience will be presented.
