Swedish Institute of Space Physics


The Swedish Institute of Space Physics is a Swedish government agency. The institute's primary task is to carry out basic research, education and associated observatory activities in space physics, space technology and atmospheric physics.

Foundation

The IRF was founded in 1957 and the first Kiruna-designed satellite experiment was launched in 1968. The institute has about one hundred employees and has its head office in Kiruna. Other offices are situated in Umeå, Uppsala and Lund.
IRF, originally the Kiruna Geophysical Observatory, began as a department within the Royal Swedish Academy of Sciences. It has been a public research institute since 1973, under the auspices of the Swedish Ministry of Education and Culture.

Satellite experiments

IRF participates in several international satellite projects. At present, data from satellite instruments are being analysed to help us better comprehend the plasma-physical processes in the solar wind and around comets and planets. For example, the Swedish Viking and Freja satellites, with equipment from IRF on board, have greatly increased our knowledge of the auroral processes in the Earth’s magnetosphere, as have the microsatellites Astrid 1 and 2, launched in 1995 and 1998. IRF's own nano-satellite Munin was launched in 2000. An IRF-built instrument on board the Indian satellite Chandrayaan-1 collected data from the Moon and new techniques for making particle measurements in space were tested on the Swedish satellite mission Prisma.
IRF has instruments on board for example the following on-going satellite projects:

Continuous measurements

Continuous measurements of the following are made at IRF
  • Earth's magnetic field
  • Aurora
  • Cosmic radio noise
  • Ionospheric parameters

    Ground-based auroral research

Experiments are conducted with research radars, such as those of the European Incoherent Scatter Scientific Association with transmitters in Tromsø and on Svalbard. These are used for example to study the processes which cause the aurora. The three-dimensional structure of the aurora is studied with ALIS, a multi-station imaging system which uses tomographic reconstruction techniques, artificial intelligence and advanced IT.

Atmospheric research

Atmospheric research at IRF focuses on studies of
Radar, optical methods, sounding rockets and balloons are used for atmospheric studies. Continuous measurements are made of:
  • Atmospheric trace gases
  • Atmospheric winds
  • Infrasonic waves.

    IRF SpaceLab

The IRF SpaceLab test facility at IRF in Kiruna, Sweden, offers industry and research groups an extensive opportunity to test and qualify space-related hardware for satellites, rockets, balloons and ground-based technology. IRF has been developing instruments for satellites, rockets and balloons since the 1960s and has all the necessary equipment to simulate the harsh environment these instruments face.
