GST is a leading provider of low-cost weather data and satellite data processing systems. GST’s systems are installed worldwide in support of public, aviation, and maritime meteorology.
DirectMet®2 is GST’s second-generation satellite data capture, display, and analysis system. The DirectMet®2 processing system interfaces with different back-end systems, including Geostationary Operational Environmental Satellite (GOES) Rebroadcast (GRB) ground stations, GeoNetCast-Americas (GNC-A) ground stations, or the Cloud (delivery of data via Internet from DirectMet®2 Cloud™) – any of which can be delivered turn-key by GST.
DirectMet®2 is built with high quality components for reliability and durability. All ingest, data processing, and analysis are performed on a single workstation with extensibility to external workstations and web browsers. DirectMet®2 is network-ready for automatic dissemination of high-quality products with Internet compatibility.
- Ingest of GRB datasets via direct readout platform for Level 1B Advanced Baseline Imager (ABI) and Level 2B Global Lightning Mapper (GLM) products.
- Optional ingest capabilities for space weather products
- Ingest configuration for GNC-A ground system, DirectMet®2 Cloud™, or remote file servers in lieu of GRB
- Effective handling and storage of large volumes of satellite data
- Automatic production of incoming GOES direct readout imagery; imagery format suitable for dissemination to Internet or publication
- Native satellite view and different map projections, defined by user for operations
- Optional platform for the creation of additional Level 2+ data products
Visualization and Analysis
- Expandable and customizable overlay database, including regional sectors
- User-defined image enhancement curves and color tables
- Automatic imagery and loop updates
- Ability to conduct forensic analysis (past storms)
- Support for multiple data formats (e.g. GeoTIFF, PNG, JPEG) for dissemination to third-party geographical information systems (GIS) or other external systems (social media, websites)
DirectMet®2 Cloud™ is a customized satellite data delivery service offered by GST. DirectMet®2 Cloud™ provides access to customized GOES-EAST imagery without the cost of obtaining a complete ground station. With DirectMet®2 Cloud™, the user can obtain GOES-EAST imagery on a regular schedule directly to the user’s operations.
This service includes the DirectMet®2 Cloud™ Viewer for visualization on any office PC or workstation. Through this service, the user has a subscription and license to receive imagery that is provided on a customized production cycle. Projections can be customized to the user’s geographic area of interest for close up view and analysis.
This service provides NetCDF4-format data directly to the user’s operation, which can be used with DirectMet®2 workstations or other Geographical Information Systems (GIS). The NetCDF4 files are produced by GST and cover the geography and GOES-16 ABI channels needed by the customer.
WAFS-METLAB2™ is GST’s second-generation weather data processing system that is an exciting way to visualize and process weather information. The WAFS-METLAB2™ workstation is independent of any data source and can be installed standalone or used in a client/server configuration. The workstation integrates many sources of government and commercially-available data, including World Area Forecast System (WAFS), Global Telecommunication System (GTS), and Aircraft Fixed Telecommunication Network (AFTN). The workstation also can ingest data from Automated Weather Observing System (AWOS) networks and GeoNetCast-Americas (GNC-A). WAFS-METLAB2™ is fully compliant to the International Civil Aviation Organization (ICAO) Annex 3 requirements.
WAFS-METLAB2™ is built with a robust data collection module that acquires WAFS data (WIFS, GIFS, SADIS) from file servers. Modules include alphanumeric data, numerical models, DIFAX, SigWx, time series, time profile, thermodynamic profile, and vertical cross-sections. Optional modules are added for satellite (including DirectMet®2), radar, and lightning. The workstation has functionality for overlays, folders, draw, alerts, print, and animation to visualize finished products. Users can create side-by-side comparisons of data products and then easily switch to alternate views that contain auto-updating product windows. Users can quickly change window configurations for different sector views as well as monitor conditions and imagery with automatic data updates. The emphasis on automatic product updating in display windows aids in monitoring changes in weather or flight conditions. Users can also personalize alerts and alarms (notifications).
BriefNet™ is a companion subsystem added to WAFS-METLAB2™ for automatic chart production, web access, and web briefings. BriefNet™ is the data processing and production engine that serves in-house analysis and then extends it to additional users who can be internal or external. BriefNet™ includes a module for on-demand production of flight folders or general briefings, which can be produced on demand for authorized users.
BriefNet™ includes webpages for Local Weather, Browse Weather, and Get Briefing. Local Weather is a webpage customized for the users to obtain latest observations and forecasts, including relevant charts. Browse Weather is a collection of all charts produced for viewing. Get Briefing is flight documentation on demand, which includes a collection of produced charts and en-route aerodrome data.
Data Collection & Handling
GST systems (WAFS-METLAB2™, BriefNet™ and DirectMet®2) include data collection software when meteorological data or satellite imagery is needed from fileserver sources. WAFS-METLAB2™, for example, is driven by data acquired from the World Area Forecast Centers (WAFC) London and Washington via the Internet. GST’s Data Collector™ software can be purchased for use by customers who need adjunct software in their operational environment to acquire meteorological data or satellite imagery from available, accessible fileservers.
GST has a meteorological message data handling system, known as the Switchboard™. This message handling system functions to acquire data from multiple sources and distribute data to multiple sources, over a variety of communication formats. There is a monitoring system for status of communication pathways and the successful transmission of messages. The Switchboard™ is well suited for operations that involve high data throughout from diverse sources, including meteorological instruments (i.e., data loggers) and fileservers. The Switchboard™ pathways connect the input sources to output destinations – which can be in any combination.
