Saphyrion is a privately owned research and development company with a focus on both semiconductor and board level designs, as well as software development. The head office is in Lugano,in southern Switzerland. Its highly educated staff, coming from major universities like ETH, EPFL, USI and Polytechnic Institute of Milan, masters a wide range of expertises in space sciences, IT, geodesy and telecoms. The business of Saphyrion is centered on high quality high value designs with a specialization in the data communication field. Saphyrion is recognized as the leading manufacturer in Europe of radiation hardened ASICs used in space GNSS receivers. Owing to their miniaturized design, the chips of the SY10XX series, available off-the-shelf, have been adopted in space missions where the reduction of volume payload is mandatory, and represent the only viable solution to provide GNSS localization capability in mini- and micro-satellites. The chipsets developed for GNSS receiver can be easily used also in RF front-ends for other types of instruments and communications equipments. At present, 60 GNSS receivers or other payloads based on Saphyrion ASICs are successfully flying, and new releas
