456200:52-04:0003:08Sams problems. All of group C bad gap with -384 in shear. Called: Katie

She came up to try to help troubleshoot the problem.
456501:09-04:2003:11During checkout I tried to go to a preset south trajectory after successfully going to Goes14 satellite trajectory. Started to get continuous 'Failed to adjust trajectory to compensate for the current tracker position' errors.
456704:20-10:2606:06After restarting everything; tried a satellite trajectory; without any interaction it failed after 12 mins. ..Error was a hexapod velocity error and a settraj failure. Actual following error and velocity error on control desk with a small skew. Did not clear in order for daystaff to investigate.


Ops Commentsnone


TO CommentsSAMS bank comm problems continued, Katie came up and tried to resolve but was unsuccessful. Tried getting on a satellite target and was successfully tracking for 12 minutes but then encountered a whole lot or errors; same issues persist as last night. High Dust at end of night


RA CommentsHad problems with the primary which prevented stacking and a skew problem on a satellite trajectory that prevented further engineering tests.
