Three fully autonomous Terma HE-5AS Star Trackers provide the precise pointing knowledge required for the main instrument, the SIRAL interferometer, on-board the CryoSat satellite. All three Star Trackers are mounted directly on the payload antenna bench of the CryoSat satellite for optimized structural stability between the star sensors and the payload sensors measuring frames.
New satelllites for monitoring the polar environment
Two types of satellite earth observation sensors are particularly interesting for monitoring the polar environment: Synthetic Aperture Radar and Radar Altimetry.
Temperature variations at Svalbard during the last century
Only a few meteorological observation series in the high Arctic are available during the last 100 years. Fortunately one of those series is located on Spitsbergen.
Projected future climate in the Arctic
The Intergovernmental Panel on Climate Change (IPCC) concluded in 2001 that man-made emissions of so-called “greenhouse gases” most likely are leading to global warming, and that the temperature incrase probably will be at maximum at high northern latitudes.

Swedish Institute of Space Physics – Uppsala
With Cluster II’s four satellites in space for the forth year in a row, Cassini in orbit around Saturn, Rosetta on its way to the Comet Churyumov-Gerasimenko and Smart-1 closer and closer to the Moon, the Swedish Institute of Space Physics in Uppsala receives large amounts of scientific data every day.
Results from First Orbit Around Saturn!
The Cassini RPWS instruments with Scandinavian participation reveals a dynamic Titan.
FFI participating electron measurements at Saturn
The Cassini/Huygens project is a cooperative effort between NASA and ESA to study the planet Saturn, its systems of rings and icy moons….
New strategic aims for ESA?
The ESA has recently undergone great changes. A new Director General is employed, a closer connection to the European Union has been established, and one has changed the structure of the organisation itself. Is this a brand new organisation, and where to from here, one may ask.
Investment in knowledge
What is the current position of the Nordic countries?
