  1. Metop-A and Metop-B at FBKS by: NOAA/Cheryl Evry Tel.: +1-301-817-4224 Mail: cheryl.evry@noaa.gov

  2. 20 Metop weekly TM/TC Proficiency Passes 1 Dec 2012 to 30 April 2013

  3. 20 Metop TM/TC Test PassesIssues

  4. Equipment Issues • Router needed reset - 1 • Cortex - 3 • TM Drops (cause not stated) - 3 • Other Issues • Pass information provided to the EPS controller team was incorrect. • Not on NOAA Schedule, configured for pass after brief. • Solutions • Schedulers now integrate passes into LEO-T • IJPS Equipment Refresh

  5. 18 Metop GDS Test Passes

  6. Issues • File did not build correctly on FXS Server • Not added to schedule (due to Priority Issue - ok) • Possible Old TLEs • Resolutions • Procedures issued for every maneuver to reload TLEs as needed. • Procedure 1303191610_metop GDS proficiency passes requesting checksums be provided for every test file • IJPS Equipment Refresh

  7. Notes • EX-4 is a model of PTP, which is a programmable telemetry processor receives the high-rate (x-band) data; breaks out packets into VCs. This would be the source of the improper time stamping and naming. • FXS is the Fairbanks Transfer Server - puts all of the VCs into one file, prepares them to send out (GDS server) • Dataflow is from the antenna to the EX-4 to the FXS. The machines set up for a pass by the FXS setting up the EX-4.

  8. Data Quality • At the beginning of this testing, only Antenna C had proper timestamping. • For Antenna A, the files are being processed/stored on the Antenna B EX-4 and FXS. Thus Antenna A and B are using the same equipment. (This will change with refresh.) •  The EX-4 on Antenna A/B was incrementing much faster than the one on Antenna C.

  9. Data Quality • The “desktops” on the EX-4’s matched between A/B and C. The registry settings on the EX-4 were also checked and matched Antenna C. • On 19 March, Fairbanks requested to put a 1PPS (1 pulse per second) unit on the Antenna A/B unit. • After that point, all files received had proper timestamping.

  10. File Naming • The old equipment can only handle M01 files but with the new equipment the file names for M01 and M02 can be handled without issue.
