LRIT/HRIT System Overview
Reliable, high performance systems for receiving and processing LRIT and HRIT data from EUMETCast, HimawariCast, GOES, GEO-KOMPSAT-2A (GK-2A) and Electro.
The Dartcom LRIT/HRIT System can receive, archive, process and display LRIT, HRIT and GVAR data from EUMETCast and HimawariCast DVB services, and GOES, GK-2A and Electro direct broadcast services.
LRIT and HRIT data is an important source of information for nowcasting, numerical weather prediction, climate monitoring and research. The latest imagery and products are available as frequently as every 5 minutes, allowing major improvements in the forecasting of severe weather.
Antenna and receiver options are available to suit different services, geographical locations and requirements. All types of transmission are supported – Ku-Band and C-Band DVB services, and L-Band direct broadcast services, including GOES HRIT, GK-2A LRIT/HRIT and EUMETCast GOES ABI level 1b services.
Ingested data can be viewed and processed using the Dartcom iDAP/MacroPro software. Outputs are also available for image processing software such as PCI Geomatica, ERDAS IMAGINE and ENVI/IDL, as well as standard interchange formats such as GeoTIFF.
The system comprises the following main components:
- Antenna – various sizes available, or customers can source their own locally, or upgrade a disused WEFAX antenna if suitable.
- Receiver – various options available to suit different services.
- Ingest and visualisation PC – running Dartcom XRIT Ingester and Dartcom iDAP/MacroPro software. Customers can either supply their own PC, or for a turnkey solution Dartcom can supply a PC fully set-up and tested.
Dartcom can also provide on-site installation and training services.
