This paper describes the design, fabrication, characterization,\udand satellite integration of a miniaturized two axis sun\udsensor which has been used in the attitude control system of the\udSpanish nano-satellite NANOSAT-1B. This device is made of four\udsilicon photodiodes monolithically integrated in a crystalline silicon\udsubstrate, protected by a transparent cover glass assembled\udon the same silicon die against space radiation damage. The sensor\udfabrication combines standard silicon processing technology with\uda high performance solar cell fabrication process. The sensor, including\udelectronics and mechanical and electrical interfacing with\udthe satellite, has a small size (3 cm 3 cm) and low weight (24 gr.),\udwith a sun field-of-view greater than \u100000 with an angle accuracy\udbetter than 0.15 . Three of these sensors have already been integrated\udin the NANOSAT-1B platform that has been successfully\udlaunched in July 2009.
