New KSATlite Ka-band antenna in operation within the Antarctic troll station – Geospatial World

A new Ka-band antenna at the KSAT Antarctic station Troll is now ready for operation and available in stores. The antenna is part of the KSATlite network and will complement the KSAT Ka-band network, consisting of 8 Ka-band antennas.

The majority of EO satellite systems continue to use X-band to download their data, but as the volume of data ingested increases, Ka-band offers high throughput, low latency, and a less congested spectrum.

KSAT is a first mover in the Ka-band and has investigated the advantages of this higher frequency band both with commercial operators such as Astro Digital and with institutional users such as NASA, NOAA and EUMETSAT.

The KSAT polar ground stations have proven to be ideally suited for the operation of Ka-band antennas. A higher sensitivity to weather influences and especially precipitation in dry areas is an important prerequisite for success.

“At KSAT we are technology-independent in our approach. Our mission is to connect space and earth and to achieve this for our customers in the most effective way, we need to continuously research and evaluate all new technologies ”, says Rolf Skatteboe, President and CEO of KSAT.

“The operational Ka-band has proven its true worth. We believe in this market. Instead of waiting for the on-board systems and customers to come first, we took a proactive approach. Implementation of new technologies based on future requirements, ”he continues.

“That’s exactly what we did for optics, where we invested in Greece and installed the world’s first commercially available optical telescope,” adds Skatteboe.

The new KSATlite antenna in Antarctica is operated as an integrated part of the KSATlite network and as part of the fully functional KSAT Polar Ka-band network consisting of 6 polar multi-mission antenna systems (4 tri-band and 2 dual – Tape). With the installation of 2 additional antennas in 2021, the KSAT Polar Ka-band network will include 8 antennas by the end of the year.

The network provides JPSS with operational services from Spitzbergen and Troll and will support EUMETSAT 2nd generation. It will also support NASA’s NiSAR and PACE missions from our stations in Svalbard, Antarctica and Punta Arenas.
