That makes sense. What kind of sensor does it use to track the stars though? Stars are very dim.

- geon 3y agoStars don’t move a lot, so exposure time can be high.
- numpad0 3y agoSimplest implementation of star trackers I've seen is the Canopus sensor[1] used in old spin stabilized satellites: the "tracker" is just a light intensity sensor and a computer on a spinning spacecraft. I don't know if that has to do with this implement or not, but a star tracker in general could be that simple. 1: http://petermasek.50megs.com/starplot.jpg http://petermasek.50megs.com/starplot.jpg
