GOES-R launched on Nov. 19, 2016 and along with GOES-S (2018) will extend the availability of the
operational GOES satellite system through 2036. When the GOES-R satellite reached geostationary orbit on
Nov. 29, 2016, it was renamed GOES-16.
On May 25, 2017, NOAA announced GOES-16’s operational location as GOES-East. The GOES-East position was
chosen primarily because it offers full coverage of the continental U.S. and provides optimal viewing of the
states and cities in the Plains, Midwest and East most impacted by severe weather events including Atlantic
Hurricanes, thunderstorms and tornadoes, major winter storms, and flooding.
GOES-16 began drifting to the GOES-East operational location of 75.2 degrees west longitude on Nov. 30,
2017. Drift was complete on Dec. 11, 2017, and nominal operations resumed on Dec. 18, 2017 when the
satellite was declared GOES-East.
The old GOES-East (GOES-13) continued to produce products distributed through GOES-14 (standby) from Dec. 7,
2017 until it turned off on Jan. 8, 2018.
GOES-S was launched March 1, 2018. GOES-17 began drifting to its GOES-West operational location of 137.2
degrees west longitude on Oct. 24, 2018. Drift was completed on Nov. 13, 2018 and nominal operations resumed
on Nov. 15, 2018. The satellite became GOES-West on Feb. 12, 2019. Changing the location from 137.0 to 137.2
degrees improved efficiency and minimized impacts from other geostationary satellites.
GOES-T was launched on March 1, 2022. GOES-18 held a two-part post-launch test with the first part at 89.5
degrees west longitude and the second part at 136.8 degrees west longitude starting on June 7, 2022. In
preparation for its eventual transition to operations, GOES-18's orbit was slowly nudged to 137.0 degrees
west longitude from July 5-21, 2022. At the same time, GOES-17 was nudged from 137.2 to 137.3 degrees. From
these locations, GOES-18 Advanced Baseline Imager data was interleaved for early imaging operations that
mitigated the GOES-17 Advanced Baseline Imager's degraded imagery due to its loop heat pipe anomaly. The two
interleave periods were Aug. 1 - Sept. 8, 2022 and Oct. 13 - Nov. 16, 2022.
GOES-U, the fourth and final satellite of the GOES-R series, was launched on June 25, 2024. GOES-19 will
complete its post-launch test and checkout activities on March 21, 2025. At that time it will commence
drifting to 75.2 degrees West, where it is scheduled to take over GOES-East operations from GOES-16 on April
4, 2025.
