My topic within IRF:

Meteors and space objects

    Research fields

  • Meteors, meteoroids, and dust
  • Mesosphere and Lower Thermosphere
  • Asteroids and comets
  • Solar-system dynamics
  • Space Safety

    Current work

  • Contribute radar observations
  • Meteoroid stream simulations
  • Space Safety research and development
  • ...

(I'm very interested to learn more about active bodies from you all!)

    Technical information

  • Frequency 233~MHz
  • Power 3.6 MW (later 10 MW)
  • 1 Tx, 3 Rx (later 5 Rx)
  • 119/55/54 Sub-arrays at sites
    (~ 10,000 antennas in Skibotn)
  • Pointing down to 30$^\circ$ elevation

EISCAT 3D

We plan to measure meteors

What about near-Earth objects?

    3 Scenarios investigated

  1. Meteoroids passing by or impacting the Earth
  2. near-Earth objects
  3. Temporarily captured NEOs (minimoons)

Results

Including meteor measurements and support instruments
EISCAT 3D can be a very good new data source

Thank you for your attention
