CubeSense Sun is a high accuracy CMOS-based fine sun sensor with a wide field of view (FOV). Optimized for low power consumption, it features a pre-calibrated distortion model, integrated processor, and has immunity to albedo effects. Its housing is designed to allow for easy and robust mounting, while providing improved EMI mitigation. Additionally, to support the high-volume production of these sensors and reduce lead times, CubeSpace (CS) has novel in-house designed and built dark optics tunnels, which allows for the concurrent calibration of multiple CubeSense Sun’s in parallel. The modular design of these tunnels makes them easily scalable based on production demands. Features: CMOS-based optical sensor 170° FOV lens Pre-calibrated distortion model Full albedo immunity Integrated processor for reduced ADCS computer processing demand Common node design Shared electronic design and heritage across Gen2 product range Random Vibration: 14.16 g RMS Radiation: 24 kRad Lifetime: 5+ Years
