NXSS3v00

A sun sensor is a navigational instrument used by spacecraft to detect the position of the sun. Sun sensors are used for attitude control, solar array pointing, gyro updating, and fail-safe recovery. The smart micro sun sensor was developed for the attitude determination system for the CubeSats space missions, The sun sensor was designed with an emphasis on the smallest possible size, while preserving its precision under <1 deg.

Additional Specifications:
• Radiation tolerant >60 krad (Si)
• Fully autonomous
• Precise, small-size and lightweight
• Own microcontroller
• Factory calibration
• Synchronous measurements by all sensors in a multiple sun sensor group, allowing for the precise description and reproducibility of all of the data.
• Ferroelectric ram data buffer
• The entire sensor is non magnetic
• Minimal space needed on the satellite surface (< 4 mm drill diameter for the sensor to detect the sun), allowing for a more efficient placement of and more place for solar panels
