Keywords:CMOS image sensor  star tracking sensor 

On Semiconductor said it will develop a star tracker CMOS image sensor with the European Space Agency (ESA).

The High Accuracy Star Tracker 3 (HAS3) image sensor will be a 1280 x 1280 pixel, radiation tolerant CMOS image sensor that features low read noise, 11 x 11µm2 pixels having 14 bit performance.

The 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, the company said.

The HAS3 will expand on the currently available HAS2, also developed by On Semiconductor.

"Following its successful qualification in 2007, ON Semiconductor's HAS2 image sensor has become the heart of a new generation of Star Trackers which have become the defacto industry standard."

According to Stephen Airey of the ESA's Control Systems Division, "ESA have been working diligently with ON Semiconductor to secure and maintain the supply of the HAS2 image sensor. We are very pleased with the level of procured wafer stock and are convinced that this is more than sufficient for the foreseeable future. ESA is looking forward to the continued collaboration with ON Semiconductor to monitor and safeguard the supply of these components while simultaneously developing the next generation products."
