HRRR Model Now Available on NOAAPort

Unisys NOAAPort and NOAAPort Gateway users who receive the NWS satellite broadcast now have access to the High Resolution Rapid Refresh (HRRR) model, being broadcast over the NWS NOAAPort network.

 

Developed over the last five years by researchers at NOAA’s Earth System Research Laboratory, the HRRR is a NOAA research to operations success story. It provides forecasters more detailed, short-term information about a quickly developing small-scale storm by combining higher detail, more frequent radar input and an advanced representation of clouds and winds. The HRRR model forecasts are run in high-resolution every hour using the most recent observations with forecasts extending out 15 hours, allowing forecasters to better monitor rapidly developing and evolving localized storms.

 

For more information, go to NOAA’s Press Release or NWS’ Technical Bulletin. For Unisys customers with annual maintenance support, you can contact Unisys Operations for help with modifying your ingest.bul file to receive the new model.

NOAAPort SBN Expansion Update – 9/24/14

To all Unisys NOAAPort Users:

 

The NWS has reported that the termination of the “old” NOAAPort downlink will occur on Tuesday, September 30th at 8:00 pm EDT (0000 UTC 10/1/14). At that time, the available bandwidth on NOAAPort will increase from the current 30Mbps to 70Mbps. The NWS has scheduled the operational dissemination of the High Resolution Rapid Refresh (HRRR) model also on September 30, 2014 (see http://www.nws.noaa.gov/os/notification/tin14-32hrrr_oper.htm for details).

 

All NOAAPort users should be transitioned over to the frequency before that time. Instructions on accessing and verifying the new NOAAPort frequency are below. Any questions or issues should be directed to: technical-support@weather.unisys.com

 

Unisys is also currently working with several users seeing above average frame losses on the new frequency. If you are seeing excessive frame loss on the new frequency, please contact technical-support@weather.unisys.com

Unisys NOAAPort Satellite Receiver Configuration Updates for NOAAPort SBN

To all Unisys NOAAPort Users:

 

As previously mentioned in an email, NOAA is expanding its NOAAPort satellite service to 70 Mbit/sec. Currently NOAA is broadcasting both the current service and the expanded service. Everyone needs to move to the expanded service by September 30, 2014. The current/old service will be terminated on September 30, 2014.

 

This expanded service is on the same satellite and transponder so there is no change to the antenna or LNB. However, a configuration change to your Novra S300 satellite receiver(s) is needed to move to the expanded service. Use the following procedure to configure your Novra S300 receiver (The same instructions have also been attached to this e-mail as a separate document):

 

Use cmcs to configure the Novra Receiver
- Log into the Unisys Noaaport Gateway
- Type “cmcs” to bring up the configuration utility.
- Type “list” to list the Novra receivers on your network
- Select the receiver you want to configure by typing the “list number” and pressing enter (note, the number does not appear when typed).
- Type the password for the receiver ( default is unisys).

 

Verify you are on the correct receiver
- Type “show sat” and look at the output
- Receiver mode is DVBS2
- Frequency is about 1154.0
- Symbol Rate is 15.119 or Auto
- ModCod is 2/3 8PSK or ANY
- Input Stream ID is 13
- Type “show traffic” several times over several minutes and verify Packets Accepted is incrementing and Uncorrectable TS packets is NOT incrementing. If TS packets are incrementing you have an RF issue.

 

Enter the NEW configuration
- Type “add pid mpe 101 102 103 104 105 106 107 108” (you may get messages for duplicate 101 102 103 104. Duplicate messages are OK.
- Type “set isi 18”
- Type “symbol auto”
- Type “modcod any”
- Type “freq 1110”
Verify the NEW configuration
- It can take up to 1 minute for the receiver to lock onto the new signal. You may need to repeat the next step a few times.
- Type “show sat” and look at the output.
- Receiver mode is DVBS2
- Frequency is about 1110.0
- ModCod is 2/3 16PSK (Any)
- Symbol Rate is 30 Msps (Auto)
- Signal Lock is ON
- Data Lock is ON
- Carrier to Noise is 14db (This varies by location and equipment)
- Signal Strength is -54dBm (This varies by location and equipment)
- Type “show traffic” several times over several minutes and verify Packets Accepted is incrementing and Uncorrectable TS packets is NOT incrementing.
- Type “quit” to exit cmcs.

 

Verify you are receiving data on your server
- If you have a Unisys NOAAPort Gateway system, type noaaport_xstats and verify the system is ingesting data.

 

Restore the OLD configuration (if necessary).
- If you have problems and need to restore the receiver back to the old configuration, bring up cmcs, select the correct receiver, and type the following configuration information.
- Type “set isi 13”
- Type “frequency 1154”
- Type “symbol auto”
- Type “modcod any”
- It can take up to 1 minute for the receiver to lock onto the new signal.
- Type “show sat” and look at the output.
- Receiver mode is DVBS2
- Frequency is about 1154.0
- Symbol Rate is 15.119 or Auto
- ModCod is 2/3 8PSK or ANY
- Input Stream ID is 13
- If you have Signal Lock and Data Lock, and the other parameters match, you are done. Type “quit” to exit cmcs.

 

Note: There is a firmware upgrade to the Novra S300, but it is not necessary in order to move to the expanded service. If you choose to upgrade the firmware you should save your configuration first because the firmware upgrade will destroy your configuration and install the default configuration. That means it will wipe out your IP addressing and passwords.

 

Additional note: The current bandwidth will remain constant (~11-15 Mbps with occasional peaks to 25 Mbps) following transition. Unisys Weather is working with NWS to get an expanded schedule of new products to be placed on the NOAAPort SBN. The first set of products will be the addition of the HRRR model, an additional ~7 Mbps starting September 30, 2014. You can monitor NWS Notifications at: http://www.nws.noaa.gov/os/notif.htm for announcements of additions and changes to the NOAAPort SBN.

 

Thank you,

Unisys NOAAPort Receiver Changes for SBN Expansion

The NWS has issued a notice to expand the current 30Mbps NOAAPort SBN service to 60+ Mbps by October 1, 2014. Details of this service expansion can be found on the NWS NOAAPort page at: http://www.nws.noaa.gov/noaaport/html/noaaport_expansion.shtml

 

Unisys has completed testing on the current Unisys NOAAPort and NOAAPort Gateway systems to accommodate this expanded service, as well as ingest of the Soumi-NPP satellite channel. Unisys NOAAPort Gateway users receiving the Unisys C-Band channel should already be upgraded to NOAAPort Version 9.0.

 

In order to receive and process the expanded NOAAPort SBN service, users will be required to update configuration settings on the Novra S-300 satellite receivers. These changes are minimal, and they do not require a firmware upgrade. Users can perform the configuration changes on CMCS using a GUI or the command line. **Detailed instructions will be provided in a later message** All changes need to be made by September 30, 2014.

 

NOAA/NWS updated messages on the NOAAPort SBN expansion can be found at: http://forecast.weather.gov/product.php?site=CRH&product=ADM&issuedby=NCF

Website Outage 7/8-7/9

The line of severe storms moving through Southeast Pennsylvania on the evening of July 8, 2014 caused the loss of internet connectivity to Unisys Weather in Malvern at approx 8:50pm EDT. This outage knocked our Unisys Weather websites offline until the internet connectivity was restored at around 9:15am on July 9.
