The revision 5 star tracker electronics are now also available. These offer even greater speed, robustness and reliability. The command-to-shutter latency is reduced by 47 msec, compared to the revision 4. The internal wire harness is replaced with a flex circuit, removing any long-term concerns of red plague or fluorine generation. The computer memories are expanded to 512 MB of SDRAM and 512 MB of NAND flash allowing for expanded star catalogs and plenty of room for customer-specific code.
