Sun Sensors

Tier Legend

Tier	Meaning
⚪	Representative or simplified Sun-sensor layout/defaults.
🔵	Hardware identity and layout are traceable; error defaults may be representative or assumed.
🟣	Blue-tier information plus source-backed measurement noise or accuracy defaults.
🟡	Purple-tier information plus source-backed bias, bias-bound, or calibration defaults.
