Comenius University in Bratislava
Faculty of Mathematics, Physics and
Informatics
1. The only higher education institute for A&A (Master, PhD)
in Slovakia
2. Own Astronomical and Geophysical Observatory in
Modra
3. Reasearch, education and development in one place
Areas of interest
1. Solar Physics – Non-thermal energy distribution of
particles in solar corona – satellites instruments
2. Small Solar System Bodies
- Meteor project AMOS (All-sky Meteor Orbit System)
- project ADAM (Automatic Detection of Asteroids
and Meteoroids)
- experiment DUSTER – stratospheric baloon sampling
of fireball dust traces (cooperation with SOSA)
3. Space Debries – astrometric and photometric obs.,
cooperation with Univ. Bern (dr. Šilha)

AMOS All-sky Meteor Orbit System
Patented and commercialised (CVTI SR, Kvant)
AMOS All-sky Meteor Orbit System
- Orbital distribution of meteoroids in close Earth’s vicinity – Meteoroid model
(application in ESA meteoroid model, coop. with SSA Programme Office)
- Spectral study of meteors in atmosphere – orbital distribution of evolved
interplanetary material
- Meteorites recoveries – example: Kosice meteorite (15the case with the
known orbit)
AMOS cameras at Canary Islands
2014 - 2015 AMOS cameras in Chile
2015 - 2016
AMOS All-sky Meteor Orbit System
Future development
ADAM-WFS Automatic Detection of Asteroid and Meteoroids – Wide Fields Survey

What and why?
- Discovery rate of NEO rises (10,000+)
- Large population “complete”, small?
- What are the orbital and size-frequency characteristics
of NEO with D between 1 – 100m ?
- How many 10 m size bodies are there?
estimates:10 mil - 250 mil
- How are they created: collisions, tidal disruptions,
delivered as small, spin-up breakup?
- Targets for mining and retrieval missions
Thank you!
