GOES-13



GOES-15 (West) is single string on Star Tracker (ST) following loss of 2nd (of 3) units on April 23, 2015

• Impact to users “almost none”

Within operational specification of plus or minus 2km. Two star trackers provided a routine navigation error of approximately .7km.

Error with one star tracker operations has been holding steady at approximately 1.4km.

• NOAA is working with NASA and the vendor to determine the root cause

• GOES-15 continues to operate with single star tracker ST3

• Looking for user feedback on impact: Vinice Tabor

GOES-13



Suomi-NPP Mission Status

• Launched on October 28, 2011, bridge from legacy POES/EOS to JPSS

• Operations of the satellite transferred from NASA to NOAA in 2013

• As of May 27, 2015 - 18,298 orbits, more than 37.8 petabytes of data

• Observations are exceeding expectation with high data availability (~99.99%)

• Named NOAA’s primary polar-orbiting weather satellite on May 1, 2014

Program Highlights: S-NPP

GOES-13



Issue

• Increased motor drive current on ATMS Scan Drive motor since 2011 Current Remains Within Limits, but the rate of increase has jumped with the last

month. Increased current means motor is working harder to drive ATMS Scan.

• Similar increases in ATMS bench test hardware have been precursors to motor bearing problems affecting the instruments functional performance.

Impact

• Increasing risk of ATMS failure over time.

Action Required

• Engineering has been monitoring issue for several months.

• Plan to gather increased resolution telemetry data on scan drive motor current. Data comes in Science Mission Data (SMD); obtaining access to SMD and Analysis

tools.

• Flight has developed a contingency plan to run scan drive motor in reverse. FVS (flight vehicle simulator) does not properly simulate the reversed scan drive

motor, cannot verify command load on FVS.Status

• Gathering increased resolution telemetry on ATMS Scan Drive Motor Current for analysis.

• Review telemetry with community and determine Action Plan.

GOES-13

Reliable Backup Water to NSOFIssue

• WSSC water main break repairs on Suitland Road sometimes requires water valve

shutoff that may or may not cause an impact to the Suitland Federal Center

Actions• Planning required by each mission system team for potential emergency shutdown

of essential and non-essential equipment.

• Planning required for emergency COOP deployment.

• Activated CIP

• Determined there was NSOF water reserves for approximately 12 hours once WSSC water is shutoff, which provide 4 hours of margin with the 8 hour estimated return to service.

• Water tankers were brought in to increase water reserves for approximately 20 hours.

Recommendations• NESDIS Facilities and GSA investigate the possibility of having a reliable backup

water source acquired such as having a well installed onsite.

• Meeting with Joint Base Andrews to discuss partnership



GOES-13

FCDAS Power AnomalyIssue

• Two sudden, major power outages brought down equipment and antennas.

March 14 – One-year-old 600A breaker feeding tech power failed due to manufacturing defect. Had to bypass UPS and generator to feed operations directly from commercial power.

March 17 – High voltage feeder fuse on commercial power transformer failed during geomagnetic storm.

Impact• Unable to support any mission.

• Significant damage to electronics in ops, comm/IT, antennas.

• Moderate damage to power distribution equipment (breakers/switches).

• Unexpected overtime, repair parts, and services. (Working on estimate for local costs.)

• No Loss of support. Data was captured by other sites.

Action Required• Replace failed breaker and damaged power distribution parts.

• Restore normal power configuration protected by UPS and generators.

• Repair damage to ops electronics and network equipment.

• Return to normal operations.

• Near-term: Review sparing status/replace spares. Add powerhouse monitoring to operations floor. Review and revise

COOP plans in accordance with lessons learned.

Status• Normal power configuration restored after coordinated shut-down March 25.

• Failed IJPS/METOP network components prevent flow of MHRPT. Equipment has arrived, installed and configured; MHRPT data has been flowing since April 6, 2015.

• Testing completed on S-NPP, JPSS, and DSCOVR. Replaced equipment for METOP. Data is now flowing out of station.

• Station nominal: all missions being supported.

Accomplishment Benefit/Impact

Successful launch support of DSCOVR – February 11, 2015

DSCOVR will maintain the nation's real-time solar wind monitoring capabilities which are critical to NOAA's space weather alerts and forecasts.

NSOF Admin LAN and ESPC IT Security Incident – Sept through Oct

Able to get basic data flows restored after unprecedented event. Lessons learned are leading to strengthened systems and procedures to keep systems from being visited by unwanted guests.

DMSP 13 Decommission

Successfully flew satellite almost 20 years. Secured satellite to prevent further damage/limit danger to other satellites. Supporting USAF analysis to apply lessons learned to operating other DMSP satellites

Wallops support for flights of Navy’s X-47B Unmanned Combat Air System.

Demonstrates OSPO’s ability to modify its operations to accommodate its Federal partners without impacting its primary mission operations.

Major Accomplishments/Events

Major Accomplishments/Events

Accomplishment Benefit/Impact

SNPP entered Earth Point Safe Mode after Drag Makeup Maneuver #18 on August 8, 2014 due to a large attitude error in the Yaw direction

Convened Anomaly Resolution Team that Root cause determined to be procedural; reassertion of mission point target attitude data before thruster burn oscillations had enough time to dampen.

Wallops experienced Radio Frequency Interference (RFI) simultaneously in the GOES-13, 14 and 15 downlinks on August.14, 2015

On 9/27, WCDAS staff confirmed Light Squared was causing the RFI experienced that day. Data collected during that event was captured and reported to the appropriate frequency management personnel within DOC/NOAA/NESDIS.
