In the spring of 2004, the GOES-P spacecraft was under construction, and will undergo thermal-vac testing in 2005/6.

As of March 2006, the GOES-P launch date was planned for 7 April 2008.

As of March 2008, the GOES-P launch date was planned for 15 April 2010.

As of November 2010, the GOES-P launch date was planned for 25 February 2010.

As of mid-January 2010, the GOES-P launch date was planned for 1 March 2010.

As of mid-February 2010, the GOES-P launch date was planned for 2 March 2010.

As of 1 March 2010, the GOES-P launch date was planned for 4 March 2010.

On 4 March 2010, GOES-P launched at 2357 UTC.


Imager SN10 was constructed and tested at ITT in Fort Wayne, Indiana circa 2000. It was delivered to Boeing Space Systems (BSS) and integrated onto GOES-P in 2005/6. There are no significant issues with the Imager.


Sounder SN10 was constructed and tested at ITT in Fort Wayne, Indiana circa 2000. It was delivered to Boeing Space Systems (BSS) and integrated onto GOES-P in 2005/6. There are no significant issues with the Sounder.


GOES-P was launched on a Delta IV with two solids to achieve at least 10 years of fuel lifetime (5 years of on orbit storage, and 5 years of operations).

If GOES-P were stored on the earth, it would have to be to be called out of 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 to less than a week, and avoids the chance of a launch failure when you can least afford it.

Orbit Raising History

March 22, 2010
Weather Satellite Is GOES-15
Boeing Satellite and Intelligence Systems operations will transition the routine health and safety monitoring to the NASA Goddard operations team on March 24.

Twelve days after a flawless launch, NASA and NOAA's Geostationary Operational Environmental Satellite-P (GOES-P) reached its proper orbit and was renamed GOES-15. The latest weather satellite will complete its checkout in mid August 2010 and be stored in-orbit, ready for activation should one of the operational GOES satellites degrade or exhaust their fuel.

"The NASA team has done an excellent job and the spacecraft performance has been near perfect. Reaching the proper orbit marks a significant milestone, but we still have a lot of work to complete," stated Andre Dress, the NASA GOES Deputy Project Manager. "We remain focused on the tasks at hand and look forward to complete mission success."

Since GOES-P launched on-board a United Launch Alliance Delta IV rocket on March 4, the satellite has undergone 5 orbit raising maneuvers before arriving at its checkout longitude of 90 degrees West, where it orbits at approximately 22 thousand miles above the Earth's surface.

NASA Engineers and controllers deployed the Solar Array on March 17 and they will turn on the Imager and Sounder on March 23. The Imager is expected to capture the first visible image on April 5.

GOES-15 is the third and final spacecraft to be launched in the GOES N-P Series of geostationary environmental weather satellites. With two operational satellites, they provide weather observations that cover over 50 percent of the Earth's surface.

Boeing Satellite and Intelligence Systems operations will transition the routine health and safety monitoring to the NASA Goddard operations team on March 24.

At this time the NASA and NOAA team will commence with the post launch verification testing, which will last for approximately 150 days. Once all the systems are checked out, the satellite will be turned over to NOAA for operational control.

NASA-to-NOAA turn-over on 1 September 2010

NOAA's plan to phase-in GOES-15 as GOES-WEST in December 2011

From: Matthew Seybold 
Date: November 10, 2011 3:28:10 PM EST
To: "ESPC.Notification@noaa.gov" 
Subject: Status of Operational GOES-West Transition Plan (GOES-11 to GOES-15), Issued: November 10, 2011, 2025 UTC

Topic:  Status of Operational GOES-West Transition Plan (GOES-11 to GOES-15), Issued: November 10, 2011 2025 UTC
Product(s) or Data Impacted:  GOES-11 and GOES-15 Imager and Sounder data and associated products, including AWIPS, ancillary communication services (DCS/LRIT/EMWIN/SAR), and GVAR data
Date/Time of Initial Impact:  December 6, 2011
Date/Time of Expected End:  N/A 
Length of Outage:  N/A 
Details/Specifics of Change:  On December 6, 2011 GOES-15 is scheduled to replace GOES-11 as the GOES-West operational spacecraft and GOES-15 GVAR will begin to flow through GOES-11 communication links.  On December 14, 2011 GOES-15 GVAR will flow directly through GOES-15 communication links and GOES-11 will be decommissioned.  A more detailed transition timeline is provided below.  Characteristics of the Imager and Sounder are similar from GOES-11 to GOES-15; however, there are some differences:
	*	Increased spatial resolution to 4 km for all IR bands
	*	New 13.3 um band
	*	No 12 um on the imager
	*	GVAR format is going from GVAR format 1 to GVAR format 3 to support 4 km band 6
	*	Ground equipment may require adjustments to satellite ID, but the transition timeline and plans are intended to minimize disruptions to users who acquire the GOES-15 GVAR signal via a ground antenna.

Changing Center Point:  The center lat/lon coordinates for GOES-15 data are changing due to the satellite drifting.  Satellite Command and Control is not able to change the image coordinates at the rate that the satellite drifts, so the image will appear to be walking off the east side of the frame.  This is not seen with the stable GOES-11 data and will not be seen once GOES-15 arrives on station at 135 degrees West and the drift stop maneuver occurs.  The location of GOES-15 can be found in WMO header TBUS10  KWBC, or on the web at http://www.noaasis.noaa.gov/cemscs/gostbus.txt

Added Scan Frames for GOES-15 Schedule:  As provided in early notifications of the adjustments to GOES-15 Routine and Rapid schedules, there will be new additional scan frames for the GOES-15 schedules.  The new additional frames will be the same domain as the current sub-conus that is taken during the GOES-11 Rapid schedule.  These frames will also adjust to the east as GOES-15 drifts: 

The timeline distributed on October 7th is still progressing as planned:  
	*	December 1, 2011.  A GOES-15 drift rate adjustment maneuver will be performed.
	*	December 6, 2011.  As GOES-15 approaches 129 degrees West, the GOES-15 transition to GOES-West will occur.  GOES-15 data will flow through GOES-11 communication links, thus, GOES-15 data becomes operational but is received through the GOES-11 downlink.  In other words, the GOES-15 GVAR data are relayed through GOES-11.  Users pointing to GOES-11 will start receiving GOES-15 data. Ancillary communication services (DCS/LRIT/EMWIN/SAR) will remain on GOES-11.  Users do not re-point antennae.  At this point GOES-15 data are considered operational, but should significant problems occur, GOES-11 data can be reestablished quickly.
	*	December 14, 2011.  A GOES-15 stop maneuver will be performed.  The GOES-11 signal is turned off and GOES-15 data are acquired directly from GOES-15.  GOES-15 GVAR data will be relayed through GOES-15. Ancillary communication services (DCS/LRIT/EMWIN/SAR) will switch from GOES-11 to GOES-15.
	*	December 15, 2011.  Pending successful arrival of GOES-15 at 135 degrees West, GOES-11 will perform de-orbit maneuvers, and GOES-11 will be decommissioned. 

These intricate steps are necessary to provide a continuous flow of data, with minimal impact to users.  There should be no need to readjust antenna unless there is a desire to acquire GOES-15 data prior to GOES-15 becoming operational.

Current GOES-15 Data
The test (development) GOES-15 server is "west.nesdis.noaa.gov".  It is currently running the normal WEST (GOES-11) schedule, but is subject to change.  When GOES-15 becomes operational in December, it will be on the satepsdist WEST servers (satepsdist3, satepsdistb3, and satepsdist3-cip). GOES-15 data are available with GWR and GCR names on west.nesdis.noaa.gov, whichever users prefer to use.  Please let us know if you have any access issues for west.nesdis.noaa.gov.  ESPC Authorized Users of GOES data should currently have access to GOES-15 data via the SATESPDIST servers under the GCR server.  GOES-15 GVAR non-operational data are currently being stored at NOAA's Comprehensive Large Array-Data Stewardship System (CLASS).

FTP Access
Current GOES-15 Data are also available for external users on the satepsanon server:  ftp://satepsanonE.espc.nesdis.noaa.gov (E is for external users). Anonymous ftp puts the client in /data/ftp/pub,  which looks like  "/"  to the anonymous ftp client.
Winds data are in /data/g15winds/  There are EE (expected error), satwnd, and knes directories.
CSBT, SFOV and other data are in GOES15/SFOV-GOES-15
