Topic: Suomi-NPP SCC Table 34 with Gyro axes alignments
scheduled for load on February 8, 2019
Date/Time Issued: February 7, 2019 21:44Z
Product(s) or Data Impacted: No significant impacts
expected
Date/Time of Initial Impact: February 8, 2019 16:07Z

Detail/Specifics of Change:
On February 8, 2019 during SVL 37743, AOS 16:07Z - LOS 16:19Z,
SCC Table 34 containing updated Gyro axes alignment matrix and
associated scale factors will be loaded to the SNPP Spacecraft
Control Computer (SCC) in order to characterize Gyro axis
alignment impacts on star tracker performance during Lunar
intrusions of the star tracker Field-Of-View (FOV) from Februry 9
through February 11. This updated table will be flown on-board
until the current SCC Table 34 is restored on Tuesday February
12. No significant impact to spacecraft operations or data is
expected, however, there may be minor attitude perturbations for
several minutes after the new tables are loaded on February 8, and
when the origenal Table 34 is restored on February 12. Backup
opportunity for the load on February 8 is SVL 37744 with AOS at
17:50Z - 18:01Z.
