About
The Fine Sun Sensor is a highly integrated module designed to estimate the sun direction vector with a precision of less than 1 degree (1 σ). It achieves this by utilizing four photodiodes. The sensor incorporates a built-in microcontroller, which facilitates connectivity to a CSP network through a CAN bus. This feature allows for seamless integration of the fine sun sensor with an attitude determination and control system (ADCS), making it suitable for various satellite applications. The product page also mentions its availability in satellites and lists several satellite platforms from Space Inventor where such a sensor would be applicable, including those for Space Domain Awareness, Geostationary BIU Microsatellites, ESM Satellite Platforms, Astro Observatory, and various CubeSat sizes (16U, 12U, 8U, 6U) for different missions like hyperspectral imaging, tactical communications, and AIS/VDES.
