FaintStar is an innovative star sensor designed for medium to high accuracy star tracking, navigation, and rendezvous operations. Its architecture includes a 1020 x 1020 pixel array with a 10 µm pitch, coupled with a 12-bit A/D conversion to deliver precise image processing capabilities. Flight-proven, it is rated at TRL9, ensuring reliability for critical aerospace missions.\n\nThe sensor supports 'light-to-centroids' image processing, a critical feature for space applications that require high precision in object positioning and tracking. Its interfaces such as SpaceWire LVDS enhance communication efficiency and data throughput, supporting speeds of 40Mb/s and 80Mb/s. Furthermore, the FaintStar is built to be radiation-tolerant, addressing Total Ionizing Dose (TiD), proton, and Single Event Effects (SEE) challenges, maintaining its performance under the high radiation levels encountered in space.\n\nThis sensor is ITAR-free and has undergone ESCC 2269000 evaluation and ESCC 9020 flight model procurement, ensuring compliance with stringent space industry standards. Its robust design and adaptability make it an excellent choice for space missions, where high accuracy, reliability, and long-term operational capability are paramount.
