The required satellite mission durations and levels of reliability have been considerably increased: While in the beginning of the 70's 3 to 5 year missions were planned, the standard is now 10 years with an expansion to 15 years and more for such programs as INTELSAT VII. Based on a 20 year test and flight experience with basically the same design, ball bearing momentum and reaction wheels with the required 15 year mission capability can be provided.
