NOAAPORT Ground Station

Complete Weather System Solution

Marta Systems’ Noaaport Ground Stations are, complete with a Satellite downlink, and a powerful data acquisition and display workstation loaded with our Yosemite meteorological software suite.

Our Windows-based Noaaport solution acquires National Weather Service (NWS) hydrometeorological data and information directly from the C-band Noaaport satellite broadcast.

The Noaaport broadcast currently contains:

  • Near real-time NEXRAD radar data from all WSR-88D Radars
  • Near real-time Radar from the Terminal Doppler Weather Radars at major US airports
  • GOES East, West and international satellite imagery
  • Many computer forecast models for the entire globe World-wide
  • UpperAir, METAR, ships, buoys and other observations
  • World-wide aviation support data
  • Virtually all text forecasts and reports generated by each U.S. Weather Service Forecast Offices
  • Ocean data, aircraft reports, and a large variety of additional data from around the world.

The Yosemite Software Suite
may also be purchased separately, configured for Noaaport, for use with customer provided RF downlinks and or server hardware.

The NOAA-Port satellite broadcast is operated by the U.S. Government to provide hydrometeorological data and information to over 150 NWS Weather Forecast Offices.

  • NOAA-Port Groundstation users enjoy timely reception of meteorological data, the reliability of a satellite broadcast, and the unrestricted royalty free use of the data, after the one-time investment in the groundstation.
  • With deployment of DVB-S (Digital Video Broadcast – Satellite), the NOAA-Port broadcast can be easily upscaled to meet the demand when new science data becomes available and delivery to the NWS field is required.
  • Hydrometeorological data and information from multiple sources are routed to the NOAA-Port Network Control Facility and processed for transmission over the following four channels:
  • GOES Channel The GOES Channel contains information from the GOES East and the GOES West satellite. The GOES East satellite is a data stream consisting of the following imagery products: visible, infrared, and water vapor for the Eastern Conterminous United States (CONUS), Puerto Rico, supernational composites, and Northern Hemisphere (NH) composites. The GOES West satellite is a data stream consisting of the following imagery products: visible, infrared, water vapor for CONUS, Alaska, and Hawaii; supernational composites, and NH composites.
  • NCEP/NWSTG Channel From the NWS Telecommunications Gateway (NWSTG), a data stream consisting of model output from the National Centers for Environmental Prediction (NCEP); the observations, forecasts, watches and warnings produced by NWS Forecast Offices; WSR-88D radar products; and most observational data over North America.
  • In addition to making all the individual WSR88D radar products available, our NOAA-Port systems can automatically generate custom National and Regional radar mosaics, including a Winter Storm Mosaics that differentiates rain, mixed, and snow.
  • NCEP/NWSTG2 Channel The NWSTG2 channel supplements the NWSTG channel.
  • Non-GOES Imagery/DCP Data Channel This channel’s data stream includes GOES DCP data, GMS/GOES-West/GOES-East/METEOSAT-5/METOSAT-7 composites for visible, IR, and water vapor products (every 3 hours), and OCONUS grids.

Satellite Downlink

The ground station consists of a 12-foot (3.7 meter) diameter parabolic satellite antenna and galvanized steel mount, C-band Low Noise Converter, antenna feedhorn, DVBS satellite data receiver, cable and lightning shunt protection. Optional non-penetrating roof mounts, antenna motor actuator and controllers are available. In operation, satellite downlink performance can be monitored in real-time. Bit Error Rate (BER), corrected BER and signal strength parameters, and network performance parameters are all available.

Data Acquisition & Display Computers

Servers and workstations are based on premium quality commercially available server computers, running either Microsoft’s Windows 7 Professional or Server 2008 R2 64-bit operating system. The computers are equipped with the latest generation of Intel multi-core processors, loaded with memory and RAID hard drives to achieve the highest level of performance and reliability. The standard system includes one computer with Windows 7 Professional 64-bit operating system.

Multi-Channel Data Acquisition

Data from the Ground Station are applied through a dedicated network interface using non-routable multicast connections to the computer for acquisition.The Noaaport satellite data stream from the Ground Station contains multiple “virtual channels”, each of which requires a “virtual receiver” in the software.

Each of Noaaport’s virtual channels carries a different type of data. As many receivers as needed can be configured within the Yosemite Software suite.

The standard system is supplied with 1 receiver that can be “tuned” to any channel. The raw received data can be forwarded on a TCP socket to other systems or software. Local data storage and TCP socket forwarding may be used simultaneously, or either may be disabled by the user.

If sufficient network bandwidth is available, TCP socket data forwarding allows the Ground Station antenna system to be located remotely from the data processing system if local conditions preclude the installation of an antenna on site.

The feature may also be used to provide redundancy in the event an antenna is destroyed or incapacitated.
