New satellite data reception system launched in the Arctic Space Centre

The Sodankylä Arctic Space Centre has a new SOD04 satellite data reception system equipped with a parabolic antenna dish (diameter of 3.7 m). The new system improves the operational capability of the Arctic Space Centre to deliver satellite data for meteorology and environmental awareness applications.

The new 3.7 m L-/X-band satellite dish (SOD04) has been installed in Sodankylä Arctic Space Centre of the Finnish Meteorological Institute. The purpose of the new SOD04 satellite dish is to replace the previous SOD01 antenna in Direct Readout (DR) data reception.

In addition to the new system, the current satellite ground segment facility at Sodankylä incorporates two high-data-rate systems with 7.3 m antennas for the reception of data transmissions from polar orbiting satellites. During 2022, the newly launched SOD04 operating at the L- and X-bands will be followed by an identical SOD05 antenna to provide redundancy, reliability and additional capacity.

The Arctic Space Centre in Sodankylä hosts the National Satellite Data Centre (NSDC) of Finland, which receives and delivers environmental satellite data and products to end-users in Finland and all around the globe. Demand for high-quality satellite data is increasing as the climate change advances and changes are occurring in environmental conditions and ecosystems. The new and upcoming updates to the satellite data reception system enable even better services and tools for environmental monitoring in the future.

The renewed satellite data reception system enables reception from new data sources

Data reception from polar orbiting EO satellites using SOD01 satellite dish has included

  • NASA EOS Aura, Aqua and Terra

  • NOAA-20 and Suomi-NPP

Data reception using the new SOD04 satellite dish currently incorporates

  • NASA EOS Aura, Aqua and Terra

  • NOAA-20 and Suomi-NPP

  • EUMETSAT MetOp-B and MetOp-C

In addition, data reception from other satellites is possible, so Sodankylä facility is prepared to receive data from new weather satellite missions, such as EUMETSAT (Meteorological Operational Satellite – Second Generation) MetOp-SG.

OMI (The Ozone Monitoring Instrument) onboard NASA’s Earth Observing System (EOS) Aura, and OMPS (The advanced Ozone Mapping and Profiler Suite) instruments onboard NOAA-20 and Suomi-NPP are utilized in monitoring and measurement of the composition of the atmosphere, see: https://sampo.fmi.fi

MODIS (Moderate Resolution Imaging Spectroradiometer) instrument onboard NASA’s Earth Observing System (EOS) satellites Terra and Aqua, and VIIRS (Visible Infrared Imaging Radiometer Suite) instrument onboard NOAA-20 and Suomi-NPP are utilized e.g. in detecting forest fires.
