2. Satellite Reliability Analysis
Satellite Reliability & Availability Analysis :
STR1-ASPI-AN-0195
Reliability requirements :
For Ku-band payload, the reliability shall be at least 0.70,
For C-band mission, the reliability shall be at least 0.60,
For X-band payload, the reliability shall be at least 0.80,
taking into account the effect of the platform reliability, at the end of its Operational Lifetime, with failure rates in accordance with the Product Assurance Requirements.

6. Single Point Failure (SPF)
Star One C1 Satellite SPFs of criticality 1 (total loss of mission) are identical to other Spacebus 3000 Satellites SPFs
Most of the SPFs can be grouped in 3 categories :
Items used during Solar Array deployment with risk of failure to release.
Mitigation : lot testing of pyro devices and safety margins
Propulsion items with risk of burst or leakage
Mitigation : proof test at unit level and/or global leak test at Maximum Expected Operating Pressure (MEOP) after Satellite environmental sequence
Structural items with risk of mechanical failure
Mitigation : safety margins
Detailed SPFs list is provided in the following slide.
Note : grey items (SPFs) exist only for Launch and Early Orbit Phase (LEOP).
