In the spring of 2004, the GOES-N spacecraft completed construction, underwent thermal-vac testing, and was ready to ship to the Cape for launch. Delays with Boeing's tests of heavy-Delta IV rockets delayed shipment to Cape Canaveral until March 2005.

Imager

Imager SN08 was constructed and tested at ITT in Fort Wayne, Indiana in the late 1990's. It was delivered to Boeing Space Systems (BSS) and integrated onto GOES-N in 2002/3. There are no significant issues with the Imager.

Sounder

Sounder SN08 was constructed and tested at ITT in Fort Wayne, Indiana in the late 1990's. It was delivered to Boeing Space Systems (BSS) and integrated onto GOES-N in 2002/3. There are no significant issues with the Sounder.

Post-launch Testing of GOES-13

Boeing performed basic engineering tests for a month after launch, and then turned GOES-13 over to NASA for performance testing in mid-summer 2006.

NASA reviewed the results of the performance testing for NOAA in December 2006, and accepted the spacecraft.

Meanwhile, NOAA carried out science & operations performance testing in December and early January, as described by the reviewers at CIRA/Colorado State University.

On 5 January 2007, NOAA turned off the instruments, in preparation for on-orbit storage.

Launch Saga

GOES-N second stage

GOES-N Launch Brochure (2006)

GOES-N was originally scheduled for launch in 2001, but construction and launch were extended to 2003, since the on-orbit satellites were working well. In 2003, the GOES-N was scheduled for launch in December 2004, and then January 2005.

In mid-February 2005, the GOES-N launch date was reset to May 2005, to avoid the risk of launching during the spring eclipse season.

In April 2005, there was a concern about the Delta IV rocket, and so the GOES-N launch was postponed to June while some tanks on the rocket were replaced.

In mid-June 2005, launch was slipped to late June to allow technicians time to check for possible damage to the Delta IV rocket's electrical systems from nearby lightning strikes.

In late June 2005, there were uncertainties about a battery in the rocket, so the launch was postponed to July.

In late July 2005, concerns about the satellite caused Boeing to slip-delay the launch several times to mid-August. On August 16th, launch was aborted with 4 minutes and 22 seconds to go.

Because launch slipped past mid-August, it was rescheduled for the first weekend in November 2005, to avoid the risk of deployment during the autumnal eclipse season in geosynchronous orbit.

At the end of October 2005, Boeing's union voted to strike, putting the launch of GOES-N on hold until the union voted to accept a new contract at the beginning of February 2006. However, the spring eclipse season would make launch risky before mid-April, so launch had to be scheduled for after mid-April.

To prepare for that, Boeing took the satellite off the fueled rocket, rehabbed both it and the rocket, and put them back together.

In early April 2006, the first launch opportunity for GOES-N was 18 May 2006.

By mid-May 2006, the first launch opportunity for GOES-N was 24 May 2006.

GOES-N launch
GOES-N was finally launched successfully right on the dot, at 6:11 pm EDT on 24 May 2006.

GOES-N was launched on a Delta IV with two solids to nearly direct injection to geo-orbit. The use of two powerful solid rocket boosters allows the main rocket to get to geo-orbit, which in turn saves fuel on the spacecraft, and achieves at least 10 years of fuel lifetime (nominally 5 years of on orbit storage, and 5 years of operations).

GOES-13 arrived on orbit with 15 years of geosynchronous station-keeping fuel.

The GOES-N spacecraft needs to have its folded solar panels facing outward towards the Sun during apogee-raising maneuvers around 1200 UTC on the other side of the Earth, which results in a Delta IV launch window around local sunset (2300 UTC) in Florida.

After launch, Boeing scheduled 24 days to get to geosynchronous orbit, deploy and outgas all components, power-up (but not open up) the instruments, and rename the satellite "GOES-13".

On June 13, after 20 days of preparation, Boeing turned GOES-13 over to NASA for the post-launch engineering checkout of approximately 240 days. The satellite will be checked out at 90W, during the 2006 hurricane season.

The first visible image was taken on 22 June 2006, 5 days ahead of schedule.

After checkout, NASA turned GOES-13 over to NOAA on 20 December 2006. NOAA will put GOES-13 into on-orbit storage at 105W until it is needed to replace GOES-12 at GOES-EAST or GOES-11 at GOES-WEST, circa 2010.

If GOES-N were stored on the Earth, it would have to be to be called out of deep storage to replace an on-orbit failure. There would be 9 to 12 months of preparation between call-up and launch, followed by 3 months of post-launch deployment and testing before it could become operational. On-orbit storage reduces this delay from one year to less than one week, and avoids the chance of a launch failure when you can least afford it.

GOES N,O,P Enhancement Summary

GOES-13 Activation as GOES-EAST in April 2010

***GOES-13 is scheduled to replace GOES-12 as the GOES-East operational
spacecraft on April 14, 2010 at 1934 UTC***

GOES-13, launched on May 24, 2006, is the first in the series of GOES-N
satellites (GOES-14 was launched on June 27, 2009 and GOES-15 was
launched on March 4, 2010). This series will carry the 5 channel imager
and 19 channel sounder similar to the GOES-I through M series, with some
differences. GOES-13 carries the same imager and sounder payload as
GOES-12, but the new spacecraft bus will allow it to operate through
eclipse and most of the keep out zone periods and images will have
increased navigation, registration and radiometric accuracy. (GOES-13
was used briefly as GOES-East in December 2008 during a thruster anomaly
period with GOES-12).

After GOES-13 becomes the operational GOES-East satellite, GOES-12 will
be moved to 60W to support GOES-South America.

The Eclipse and Stray Light Zone schedules have been modified to include
an extra day of Partial Frame testing, as well as continued GOES-11 Full
Disk scans up until April 29, 2010. These updated schedules can be found
at: http://www.ssd.noaa.gov/PS/SATS/eclipse.html
(Users of NOAAPORT/GINI will continue to see GOES-11 Full Disk in place
of the GOES-13 Partial Frames between 0430 UTC and 0545 UTC until 4/29/10)

Partial Frame definitions and updated GOES-East schedules for GOES-13
can be found at: http://www.ssd.noaa.gov/PS/SATS/GOES/THIRTEEN/sched.html

The plans developed are intended to cause as few disruptions as possible
to all users who need to acquire the GOES-12 GVAR signal via a ground
receive antenna, while also allowing for the acquisition of GOES-13 GVAR
data for 2 months prior to becoming operational to re-validate ingesting
equipment and product generation.These plans are similar to the GOES-8
to GOES-12 transition plans in April 2003.
An up to date synopsis:

(1) On 2/23/10, The Office of Satellite Operations began the eastward
drift of GOES-13 at approximately 0.5 degrees per day. Navigation
elements can be found at NOAASIS ( http://noaasis.noaa.gov/NOAASIS/ ) or
more specifically at: http://noaasis.noaa.gov/cemscs/navsum.txt . Daily
longitudinal positions can be found at the end of this notification.

(2) GOES-13 SXI was activated on 3/8/10

(3) On 4/14/10, GOES-13 will approach 81W. At 1834 UTC, GOES-13 GVAR and
LRIT will be relayed through the GOES-12 downlink. Ancillary services
(DCS, EMWIN, SARSAT) will remain on board GOES-12. GOES-13 will be
declared GOES-East in the NOAA GOES Constellation. Users with fixed GVAR
or LRIT antennae will not need to re-point to GOES-13. GOES-13 GVAR
format is similar to GOES-12 (GVAR format change will occur with GOES-14
and beyond).

(4) On 4/26/10, GVAR and LRIT downlinks will be switched from GOES-12 to
GOES-13 when GOES-13 is at 75.5W. GOES-13 will stop drift. Ancillary
services (DCS, EMWIN, SARSAT) will switch to GOES-13 at this time.
Additional information about DCS transition can be found at:
http://www.ssd.noaa.gov/PS/SATS/GOES/THIRTEEN/GOES-13_DCS_Notification.pdf

(5) On 4/27/10, GOES-12 will begin eastward drift to 60W in order to
replace GOES-10, which was de-orbited in December 2009. Imaging
operations for GOES-South America will begin on or about 5/11/10.
GOES-12 is expected to arrive on station at 60W on 5/17/10.

Users of GOES data and products from ESPC:
ESPC is ingesting GOES-13 GVAR and hosting it on McIDAS server
West.nesdis.noaa.gov under the group GCR. In addition, OSDPD plans to
re-validate product generation and distribution, including that of the
GOES Ingest and NOAAPORT Interface (GINI). Product Area Leads will be
responsible for coordinating with specific users on where they can
obtain GOES-13 products.

We will provide periodic updates to this transition plan as milestones
are met, or any deviations from the schedule are anticipated. Updated
information will be posted to: http://www.ssd.noaa.gov/PS/SATS/

GOES-13 Imager and Sounder Anomaly in September 2012

The Sounder and Imager were taken offline after the radiometric data became noisy and the scan motors signalled overload.

Topic:: GOES-13 Sounder Instrument Anomaly

Date/Time Issued: September 24, 2012,  1740 UTC
Product(s) or Data Impacted:  GOES-13 Sounder

Date/Time of Initial Impact: September 23, 2012   1120  UTC

Date/Time of Expected End:   Unknown

Length of Outage: TBD

Details/Specifics of Change: No Sounder products will be available due to an 
instrument anomaly.  A return to service is unknown. The problem is being 
investigated. 

Update#1  GOES-13 Sounder instrument anomaly continues the Engineers are on 
site, with no return to service time available.

Update#2  GOES-13 Sounder instrument anomaly status has not change, the 
Engineers continue to investigate. The estimated return to service for GOES-13 
Sounder is still undetermined at this time.

Update#3  GOES-13 Sounder instrument anomaly status has not change.  The 
Engineers continue to investigate, still with no return to service time available.

Update#4  GOES-13 Sounder instrument anomaly status has not change and the 
investigation continues,  with no return to service time available.

Update#5 Due to the GOES-13 anomaly both the Imager and Sounder are being placed 
into standby mode. There will be no products generated by GOES-13. The  East 
GINI  was switched to the alternate mode. This means that the East GINI is using 
GOES West data for processing/creating products.

Update#6:   GOES-15 Full Disk images will be transmitted thru the GOES-13 GVAR as of 0030 UTC.  

Status: Imager out of service  since  September 23, 2012 at 2122 UTC
Sounder out of service  since September 23, 2012  at 1126 UTC
LRIT East out of service  since September 23, 2012 at 2122 UTC

The Engineers continue to investigate, no return to service time available.

Topic: GOES-13 Return to Operational Service as GOES-East and GOES-14 Drift Stop Maneuver

Date/Time Issued: October 16, 2012 at 2038 UTC

Product(s) or Data Impacted: GOES-13 and GOES-14 Imager and Sounder Data, GVAR Data

Date/Time of Initial Impact: October 18, 2012 at 1444 UTC - Switch to GOES-13 initiated.

Date/Time of Expected End: October 18, 2012 at 1445 UTC - Switch to GOES-13 completed.
Note:  GOES-14 Drift Stop Maneuver will be executed October 19, 2012 at 1356 UTC

Length of Outage: See Details.

Details/Specifics of Change: Tests of GOES-13 instrumentation have demonstrated the imager
and sounder are ready to return to GOES-East operational service.  GOES-13 Imager data are
nominal and thanks to outgassing activities the noise in GOES-13 Sounder shortwave data
has been reduced compared to pre-anomaly levels.  The return of GOES-13 to operational
service also optimizes the long term continuity of the GOES constellation.

On October 18, 2012 at 1444 UTC GOES-13 data will be inserted back into the GOES-13 GVAR
data stream, replacing the current GOES-14 data stream.  Users do not need to repoint
their antennas as the switch of GVAR data streams will be transparent.  Users will notice
the immediate shift of Earth coverage from the current GOES-14 drifting position to the
GOES-13 position at 75 degrees West longitude.  GOES-East products will be generated using
GOES-13 and will receive nominal 24x7 monitoring.  GINI and Remapper output will be
monitored to ensure nominal GOES-East coverage of the CONUS for users of AWIPS and for
users of the SATEPSDIST servers within ESPC.  Products requiring a climatology of 30 days
will not be generated until the requisite number of fixed satellite location days have
passed: - ASDTA SMOKE (Automated Smoke Detection and Tracking Algorithm) - GASP (GOES
Aerosol and Smoke Product) - GEO-SST (No NETCDF format) - GSIP-FD (GOES Surface Insolation
Product-Full Disk)

RSO and SRSO schedules from GOES-13 will be available to the NWS immediately after the
switch is completed.  A final stop maneuver of GOES-14 will occur on October 19, 2012 at
1356 UTC placing it at a position of 89.5 degrees West longitude where it will remain in
standby until further notice.
