Context

Currently, space and ground based instruments are too few, too expensive, and not precise nor reliable enough to meet the growing needs of the market, as identified by the International Committee for Space Research.

Technology

Entry of the upper atmospheric glow by a collector

  • Passage through a continuous rotating polarization filter
  • Filtering to select the wavelength to be observed
  • Focusing on the sensor
  • Entry into the photomultiplier sensor to be transformed into electric power. The measurement of the polarization parameters (angle and degree) makes it possible to access the ionospheric currents and the variations of the external magnetic field. IPAG (Institute of Planetology and Astrophysics of Grenoble) has developed a new technology for large scale direct measurement and monitoring of the space environment, based on the analysis of the thermosphere and the geomagnetic field (and their variations).

Advantages

  • Global and continuous coverage
  • Operational in any weather conditions
  • Lightweight, compact, modular, autonomous and transportable instrument

State of progress

A demonstrator has been successfully developed in laboratory and tested since one year under real conditions:

  • In the auroral zone
  • At mid latitude in the Alps
  • In the polar zone

Applications

Potential applications are wide and growing: telecommunications, positioning, space, aeronautics, defense, drilling, geophysical data providers, space weather actors, electricity networks .
