*Details/Specifics of Change: *
As of 1900z Jun 19, Star Tracker 2 on GOES-15 remains offline.GOES-15
remains fully operational as GOES-WEST, utilizing a single star tracker
to maintain attitude control.Product accuracy continues to remain
within
specifications approximately 95% of the time.
GOES-15 continues to operate nominally with single star tracker.A
GOES-15 E/W stationkeeping maneuver was executed at 1250z on June
18.Single-star-tracker attitude control during the maneuver and
post-maneuver imaging performance were all nominal.
Boeing, Ball, and NOAA engineers are developing a test procedure to
validate star tracker subsystems.Implementation of the test has been
delayed due to Critical Weather Days, and is planned to be implemented
next week.
NOAA engineers continued to make changes for single-star-tracker
command
procedures and scripts.They have submitted a single-star-tracker
stellar
acquisition script and a single-star-tracker thermal command procedure
to Boeing for peer review.On June 19, Boeing presented single star
tracker stellar acquisition simulation data to NOAA and NASA.

In the absence of a significant change of status, the next status
update
will be published on Friday, Jun 26th.
