The Redwire Coarse Sun Sensor (CSS) (Cosine Type) is a small, lightweight sun sensor that offers approximate cosine and conical symmetry Field-Of-View (FOV) capabilities.
Key features of the CSS include:
- Single detector
- FOV: approximate cosine, conical symmetry
- Baffles can be provided to restrict the FOV
- Rad hard >100 krad (Si)
Applications of this sun sensor include:
- Solar-array pointing
- Sun acquisition
- Fail-safe recovery
Redwire can provide baffles to restrict the FOV. Nearly any FOV can be accommodated by a unique baffle for the CSS. Typically, the customer defines the particular FOV needed to shield the detector from any stray light reflections. Redwire designs the baffle to meet this stray light FOV, while maximizing the active FOV of the detector. For complex baffle designs, a prototype baffle is typically built and verified by test.
The CSS has signficant flight heritage on the following missions:
- Mars Phoenix
- EMM (Hope)
- Fermi (GLAST)
- Deep Impact
- Classified Programs
Sun Sensors are export controlled through an ECCN (Export Control Classification Number) issued by the United States Department of Commerce, ECCN 7A104. Export shipment requires successful application for an export license. Redwire is AS9100D/ISO 9001 certified.
