BMH Scope and Benefits
• Objective:– Migrate NOAA Weather Radio (NWR), Console Replacement
System (CRS) functionality into AWIPS II infrastructure
• Benefits:– Leverages AWIPS Infrastructure and support to improve BMH
system robustness, availability and maintainability vs. CRS• Mitigates risk of depending on aged, custom CRS H/W and S/W
– Enables extensibility to allow for future enhanced capabilities– Transition to BMH transparent to NWR end users except
potentially improved voice quality

• NOAA Weather Radio (NWR)• 24/7 broadcast of NWS and Federal products• ~1000 NWR transmitters in use• NWR receivers (radios) allow anyone to listen
• Hazard display• Alert tones (1050 Hz)• Auto on when critical warning products are broadcast

NWR Overview
• Console Replacement System (CRS)• Currently used at WFOs• 15-20 year old hardware and software
• Maintainability challenges• Not extensible
CRS is outsideAWIPS boundary

NWR/BMH Software Design
• Makes use of AWIPS II architecture– redundancy/failover (parallel ops on PX)– staff will be familiar with AWIPS II– less training– flexible/extensible/expandable
• Leverage existing AWIPS II code/packages– qpid– Alertviz– logging– GUIs/CAVE– Plug-in development

BMH Schedule
• Software Development: January, 2015
• System Testing: January – March 2015
• Operational Test and Evaluation (OTE): April – July 2015
• Begin Deployment: September 2015
