Dartcom is pleased to announce the availability of its new HimawariCast LRIT/HRIT System to provide reception of LRIT and HRIT data from the new HimawariCast service. The first system was recently installed and commissioned at the Central Weather Bureau, Taiwan.

HimawariCast is a new C-Band DVB service operated by the Japan Meteorological Agency (JMA) disseminating data from the new Himawari-8/9 satellites. It is a replacement for the L-Band direct broadcast MTSAT LRIT and HRIT services which will be terminated in November 2015 due to the MTSAT-1R satellite reaching the end of its operational life.

In the mean time HimawariCast will operate in parallel with the direct broadcast services, transmitting the MTSAT LRIT and HRIT datasets. This provides users with a period to transition smoothly between existing MTSAT direct broadcast systems and replacement HimawariCast systems.

Once the MTSAT direct broadcast services have been terminated, the HimawariCast repeat cycle time will decrease to 10 minutes for both LRIT and HRIT (currently 30 minutes for HRIT and 60 minutes for LRIT) and the number of image bands on the HRIT service will increase to 14 (currently 5).

Users with MTSAT direct broadcast systems should start replacing them now with HimawariCast systems to ensure they are ready for the transition in November. Please contact us to discuss your requirements or request a quotation.


Dartcom launches affordable X-Band EOS System for Terra, Aqua, Suomi-NPP and FY-3

Dartcom is pleased to announced the availability of its new X-Band EOS System, a low cost, compact solution for receiving and processing direct broadcast data from X-Band earth observation satellites, including Terra and Aqua (MODIS), Suomi-NPP and FengYun-3 (FY-3).

The system is aimed at universities, research institutions and other organisations with limited budgets and restricted installation sites. However Dartcom has not sacrificed performance and features, as Chief Electronics Engineer Dave Wright explained. “We use a 1.5m radome enclosed antenna with carefully chosen RF components, tight tolerances and our own tracking and ingest software. Extensive testing proves that good data reception is possible from 5 degrees elevation and the antenna operates normally in wind speeds up to 185km/h”.

The Remote Sensing Laboratory at the University of Valladolid, Spain (LATUV) is one of the first customers to benefit from a Dartcom X-Band EOS System. LATUV’s Director and Professor of Applied Physics José-Luis Casanova Roque said that since installation of the system in April 2014, “it has never lost an image or presented any kind of problem even during times of intense rain or strong winds. This is excellent equipment and displays an unexpected level of operation and extraordinary performance for a system of this size.”
