Cory Posted December 10, 2010 Share Posted December 10, 2010 They'll be doing a test today to try to avoid another incident similar to a few days ago, where dataflow was lost due to interference from the out-of-control Galaxy-15 satellite. Info on the bad satellite: http://www.space.com...eat-101015.html http://weather.noaa.gov/tgstatus/ NOXX01 KWBC 101332 TO ALL NOAAPORT-SBN CUSTOMERS . NOAAPORT-SBN -- GALAXY 15 -- UPDATE 001 RETRANSMITTAL . THE INTERFERENCE RISK IDENTIFIED BY THE NOAAPORT-SBN SATELLITE PROVIDER DUE TO THE GALAXY 15 SATELLITE IS SCHEDULED TO --FLY BY-- SOMEWHERE BETWEEN DEC 12TH AND DEC 18TH . CURRENT PROJECTIONS HAVE THE INTERFERENCE TAKING PLACE AROUND WEDNESDAY DEC 15TH. . THE FOLLOWING PLAN IS BEING FINALIZED TO MITIGATE IMPACT TO OUR CUSTOMERS . 1. THE AWIPS NOAAPORT-SBN DATA WILL BE ROUTED VIA ITS NORMAL PATH THROUGH THE CURRENT PRIMARY AWIPS MASTER GROUND STATION . 2. THE AWIPS PRIMARY MASTER GROUND STATION WILL BROADCAST THE SIGNAL FEED THROUGH A DIFFERENT SATELLITE FOR ROUTING TO ANOTHER MASTER GROUND STATION IN THE PACIFIC. . 3. THE AWIPS NOAAPORT-SBN DATA WILL THEN BE RE-BROADCAST VIA THE MASTER GROUND STATION IN THE PACIFIC USING THE PRIMARY SATELLITE FREQUENCY AND THEN DOWN LINKED USING CURRENT AWIPS NOAAPORT-SBN PARAMETERS. . AFTER CONFIRMATION IS RECEIVED THAT GALAXY 15 CAN NO LONGER INTERFERE WITH THE AWIPS PRIMARY SATELLITE ALL SERVICES WILL BE RETURNED TO THEIR NORMAL CONFIGURATION. . A TEST OF THE INTERFACE FOR THIS MITIGATION PLAN IS SCHEDULED TO TAKE PLACE TOMORROW --DEC 10TH-- 2000Z TO 2200Z. THE TEST WILL CONSIST OF MOVING THE AWIPS NOAAPORT-SBN DATA FLOW OPERATING OUT OF THE BACKUP MASTER GROUND STATION IN FAIRMONT WV TO THE TEMPORARY PATH THROUGH THE PRIMARY MASTER GROUND STATION OPERATING OUT OF HAUPPAUGE NY. . TO ALSO MINIMIZE IMPACT TO DATA FLOW THE PRIMARY AWIPS NOAAPORT-SBN SIGNAL PATH WILL BE AVAILABLE FROM THE BACKUP MASTER GROUND STATION IN FAIRMONT WV. . IF THE TEST INTERFACE MEETS ALL EXPECTATIONS NWS WILL LEAVE ALL CUSTOMERS ON THE ALTERNATE PATH FOR THEIR AWIPS NOAAPORT-SBN DATA UNTIL THE GALAXY 15 RISK IS NO LONGER A CONCERN - EXPECTATIONS ARE FOR THIS SERVICE REALIGNMENT TO END ABOUT DEC 18TH . ADDITIONAL INFORMATION WILL BE PROVIDED REGARDING THIS POTENTIAL PROBLEM AS MORE INFORMATION IS MADE AVAILABLE. IF YOU HAVE ANY QUESTIONS, PLEASE CONTACT THE NWSTG AT 301-713-0902. . YOUR PATIENCE WITH US DURING THIS EVOLUTION IS GREATLY APPRECIATED. . NWSTG . P.S.

snowman21 Posted December 10, 2010 Share Posted December 10, 2010 Makes you wonder why they are still using satellites when we have the internet. Link to comment Share on other sites More sharing options...
Cajun Thunder Posted December 11, 2010 Share Posted December 11, 2010 Makes you wonder why they are still using satellites when we have the internet. Because phone lines are less reliable than satellites. Link to comment Share on other sites More sharing options...
tmagan Posted December 11, 2010 Share Posted December 11, 2010 I'm not far from Hauppauge, NY. I'm wondering where that ground station is? Link to comment Share on other sites More sharing options...
Typhoon Tip Posted December 11, 2010 Share Posted December 11, 2010 Because phone lines are less reliable than satellites. more internet traffic is run through satellite anyway. wow Link to comment Share on other sites More sharing options...
wall_cloud Posted December 11, 2010 Share Posted December 11, 2010 yeah, the satellite frequency was halted for several hours a few days ago but that was taken care of. We still haven't seen the effects of this satellite yet so I'm crossing my fingers that it doesn't happen a critical weather time (not for us since it doesn't rain here anymore!)
