Does anyone know of a COTS star pattern identification software?
Does anyone know of a COTS star pattern identification software?
Obviously, 'lost in space' will also work (might be more expensive, though). References to literature/descriptions of relevant algorithms would also be very useful. Note: I am looking for a little more detail than "make triangles out of star centroids in the image, measure the distance between centroids in the triangle, then compare with a database of same, generated from a star catalog (correcting for proper motion)." Thanks! |

Ball will apparently gleefully sell you a system, but when I talked to one of their engineers some years ago he didn't want to be any more specific than that - evidently they figured that their details were proprietary. Hint from debriefing the Astro project' scientists - be really sure of your star catalog's lineage and the camera's wavelength span of sensitivity if you want to include an intensity cut for star IDs.

Not to mention actually simulating the star tracker in all orientations to ensure that the catalog is actually dense enough to not have embarrasing gaps. |

Lockheed-Martin made the star trackers for Spitzer, which are similar in principle to the Ball CT-601 but deliver sub-arcsecond accuracy. I'm not sure who made the Chandra star trackers, but it must be possible to find out. Of course when dealing with any large aerospace company, bring money. I don't know the price of a CT-601, but my guess would be 7 figures and the first digit 1. |

You might want to ask Henry Spencer ( henry at zoo.utoronto.ca ) what they used on MOST http://www.astro.ubc.ca/MOST/ The amsat http://www.amsat.org/amsat-new/index.php folks might also have some recommendations. |
