Sweden modernizes its Ka-band system |

The Swedish Space Corporation (SSC) upgraded its polar and equatorial locations to support Ka-band data reception and deployed a global Ka-band network primarily focused on Earth Observation (EO) missions. This important step will allow EO missions to use higher bandwidths and receive larger volumes of data, allowing space companies to use their assets more efficiently.

The upgrade covers SSC’s strategic locations in Punta Arenas in Chile, Sri Racha in Thailand, Inuvik in Canada and Esrange in Sweden, as well as the SSC partner station in Weilheim, Germany.

The network upgrade builds on recent work where Ka-band capacity was added to SPC’s polar sites in Canada and Sweden. While polar stations provide large volumes of data with good latency, equatorial stations allow increased volumes and provide timely coverage for selected regions. The expansion continues as the company plans additional Ka-band antennas, starting with the two new radome antennas introduced in northern Sweden in 2021.

“We are very pleased to present the world’s first Ka-band network for Earth observation missions. SSC always strives to offer ground support that reflects the size and ambitions of the market. This investment responds to the growing demand for higher throughput capacity for Earth observation missions, ”said Miranda Pirrie, President of Satellite Management Services at SSC.

“By operating a global network that contains both polar and equatorial stations with a high level of redundancy, we are strengthening our position as a leading provider of ground connectivity for Earth observation operations. But it doesn’t stop there, we continue to strengthen our network to offer the most advanced technical properties ”, says Patrik Melvås, Head of Business Development SaMS at SSC
