GOES-West Alternate RSO Restored

As a result of recent testing, at NESDIS, the NWS and CIMSS, GOES-15 (West) is once again able to call Rapid Scan Operations (RSO) over Hawaii

RSO was then called for almost 6 days to monitor Tropical Cyclone Ana

A correction that re-claims previously missing Sounder data was developed by OSPO, working with Exelis and others. These re-claimed data were provided, and then qualitatively and quantitatively analyzed at CIMSS. This correction is now operational (March 2014).

GOES-14 Super Rapid Scan Operations (SRSOR)

GOES-14 provided very unique data and offered a glimpse into the possibilities that will be provided by the ABI on GOES-R in one minute mesoscale imagery

GOES Product Impacts

GOES-13 SXI detector damaged due to 2006 flare. 9 rows currently affected out of 512 total.

GOES-14 products are all nominal.

GOES-15 Sounder temperature control blanket is raised. - Requires a yaw flip at

Equinox to keep Sun angle below cooler plane.

- 1 hour data outage and degraded products during 26 hours of INR recovery.

GOES-13 XRS X-ray measurements can potentially invert unexpectedly.

GOES-12 Decommissioned

o W:

May 10, 2010 – Aug 15, 2013Decommissioned: Aug 16, 2013Extensive end-of-life Sounder filter wheel

testing was conducted toggling filter wheel windings and electronics

Single string thrusters were used to boost GOES-12 350 km above GEO orbit

GOES-12 captured this visible image of Hurricane Katrina shortly after landfall on August 29, 2005.

Sample coverage from GOES-12 imager when at 60 degrees West

GOES-15 Star Tracker 1 Failure

GOES-15 Star Tracker 1 (ST1) failed - caused GOES West schedule to be disabled on Jul 15, 2014

GOES West scan operations resumed 6 hours later and the S/C was running with single star tracker (ST3)

Short Span Attitude Adjusts (SSAA) were enabled to maintain Image Navigation and Registration (INR) operations

ST2 was powered on and configured for ST2-ST3 on Jul 17 S/C is performing nominally as GOES West

19

Improved Eclipse Operations

• GOES-15 experienced a 37 km grid shift on Sep 9, 2013. Degraded star measurements caused by corrupted stars produced a bad eclipse IMC set.

• During eclipse, star measurements degrade due to thermal shifts in the secondary telescoping mirror and “potato chipping” of the scanning mirror.

• The OATS software was modified to account for the double peak stars during eclipse.

• This software correction will protect against a similar situation in the future.

GOES cloud products go into RTMA which is used to verify NAM and GFS. • The GFS is used for boundary conditions for regional models.

GOES-13 Momentum Anomaly

S/C lost attitude knowledge and was transitioned to safe hold on May 22, 2013

Anomaly was caused by physical momentum exchange

Torque plane analysis suggests the most probable cause is micrometeoroid/space debris hit on the lower yoke

S/C recovered to normal mode operations on May 29 and all units are operating nominally

S/C Sounder outgas performed from May 31 - June 4

S/C is performing nominally as GOES East since June 10, 2013

GOES-14 was brought out of storage and served as GOES East from May 23 – June 10
