It enables instruments of a couple of tens of grammes. Next to consumer market sensors that doesn't seem much, but for space this really is a big deal.<br /><br />And what is the next step? A star tracker on a chip?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-3061624956116703512011-03-15T11:42:39.891+02:002011-03-15T11:42:39.891+02:00Weight, power dissipation, size to name a few.

Sun sensors are coarse attitude sensors, compared to star trackers.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-50747237469219259712011-03-15T09:59:47.786+02:002011-03-15T09:59:47.786+02:00What are the critical performance requirements in ...What are the critical performance requirements in such device?
