Summary
The NCSS-SA05 is TRL 9 with in-orbit heritage since 2014, with around 60 units delivered globally. The NCSS-SA05 has been used on several international programmes including a lunar mission.
The NCSS-SA05 is based around a PSD analogue sensor. Each sensor comes with a specific calibration equation for maximum accuracy. The unit can be powered from unregulated DC power from the spacecraft.
Key features of the NCSS-SA05 include:
- Low mass
- Low power
- PSD architecture
- Analogue interface
The NCSS-SA05 can be used in a range of applications, including:
- Accurate determination of sun-angle
- Can be used in conjunction with a magnetometer for simple attitude control
- Can be used as safe-mode sensors on gyro or star-mapper controlled systems
- Six sensors can achieve full sky coverage
