The European Space Agency (ESA) has awarded a joint development contract to ON Semiconductor for a next generation star tracker CMOS image sensor (CIS). Once developed, the High Accuracy Star Tracker 3 (HAS3) image sensor will expand ON Semi’s STAR family of radiation-tolerant CISs.
The existing HAS2 CIS offered today by ON Semiconductor is designed for Attitude and Orbit Control (AOCS) space applications. The HAS2 was developed and qualified under the General Support Technology Programme of the ESA. The device features an array of 1024 x 1024 active pixels (18 µm) and supports on-chip non-destructive readout and multiple windowing. Following its successful qualification in 2007, ON Semiconductor’s HAS2 image sensor has become the heart of a new generation of Star Trackers.
The HAS3 next generation CIS to be jointly developed by ON Semiconductor and the ESA is expected to provide advanced sensor technology. The HAS3 will be a 1280 x 1280 pixel, radiation tolerant CMOS image sensor that features low read noise, 11 x 11 µm2 pixels having 14 bit performance. The HAS3 sensor will support multiple windowing, will be made available in a fully hermetic sealed package and has the option for backside illumination. Applications for the HAS3 device will include star trackers, sun sensors and other scientific applications.
