MP: MAY2917L ORV DOT Acceptance Test Load Review today at 2pm. Eng: At the beginning of May a software patch to reduce the OBC star measurement residual threshold from 20 to 5 arcsec has been uplinked. In case of larger initial errors this made us susceptible to autonomous star re-acquisition following the initial Kalman phase. We had 3 cases of such an autonomous star re-acquisition so far. These are normal and safe operations, just different from what we saw before uploading the patch. GOT: 11238 OFLS 12.2.2.1 system has been installed yesterday.
