*Topic: *NOAA-17 End of Life: GYROLESS Enhanced Flight Software
On-Orbit
Testing **
*Date/Time**Issued:*February 27, 2013, 2140 UTC
*Product(s) or Data Impacted:*All data and products from NOAA-17
(AVHRR, AMSU-A, HIRS, AMSU-B, & SBUV) **
*Date/Time of Initial Impact:*February 26, 2013, Time 15:52 UTC
*Date/Time of Expected End:*March 07, 2013, Time 15:39 UTC **
*Length of Outage:*9 Days***
*
*Details and Specifics of Change: *A test of the enhanced Gyroless Yaw
Estimator (GYE) software will be performed on NOAA-17 beginning on
February 26th and ending on March 7th. GYE has not been previously
tested on NOAA-17.
On February 25, 2013 a test of GYE flight software will begin and
continue until March 7, 2013. This is one of the scheduled End-of-Life
tests for NOAA-17 prior to the proposed deactivation on March 20. It
will also be the first GYE test of extended duration lasting more than
48 hours. Spacecraft yaw pointing accuracy is not expected to be
significantly changed since the spacecraft already operates in the ESTX
(estimate yaw) mode. Yaw errors in GYE may be in the range of about ± 1
degrees. The test will run for about 9 days. Recall NOAA-15 and
NOAA-18
have been tested for 24 to 48 hour period in GYE with the resulting
expected errors quoted above.
This test will proceed during Critical Weather Day Periods since the
proposed decommissioning date for NOAA-17 is 20 March 2013.
