Subject: Administrative: GOES-16 longitude offset test scheduled --001a11472580bab68a0555b62f2f Content-Type: text/plain; charset="UTF-8" Topic: GOES-16 longitude offset test scheduled for August 7-September 1, 2017 Date/Time Issued: August 1, 2017 1930 UTC Product(s) or Data Impacted: GOES-16 ABI and GLM Data and Products Date/Time of Initial Impact: August 7, 2017 2331 UTC Date/Time of Expected End: September 1, 2017 Length of Outage: N/A Details/Specifics of Change: In order to test the sensitivity of GOES-16 products, a multi-day longitude offset test will occur August 7-September 1, 2017. All instruments, product generation, and product distribution will remain in nominal modes and configuration throughout the test. The test consists of two separate time periods: 1) August 7-18, 2017: GOES-16 will move from 89.5 degrees West to 89.2 degrees West 2) August 18-September 1, 2017: GOES-16 will move from 89.2 degrees West to 89.3 degrees West After September 1, 2017: Depending upon the test results, GOES-16 will either remain at 89.3 degrees West or return to 89.5 degrees West for the remainder of Extended Validation into November, 2017. Information on the subsequent GOES-16 drift and transition to GOES-East will be provided at a later time. Although the spacecraft will be moving during this test, products and metadata will continue to report a position of 89.5 degrees West. This test will allow an opportunity to intentionally assess the sensitivity of the instruments, ground segment, algorithms, and science products to a change in GOES-16 longitudinal orbit. Although minimal impacts to science products are anticipated, the actual impact will be assessed during the test. Some degradation of image navigation accuracy may occur. User applications which rely on metadata fields may also experience anomalies. GRB antennas properly peaked for the current position at 89.5 degrees West, should see no impact from this test. Total pointing loss will be less than 1 dB for the maximum longitudinal difference of 0.3 degrees.
