Welcome to UST documentation page

This site documents instruments developed by Universal Scientific Technologies s.r.o. for atmospheric and electromagnetic research. The instruments cover the full chain from lightning detection and electric-field sensing to integrated mobile and airborne measurement platforms.

What you can find here?

• Radio Storm Monitoring Stations (RSMS) — VLF and UHF SDR receivers for lightning observation, including a distributed VLF lightning mapping algorithm and the lightning trigger theory.
• Electric Field Sensors (THUNDERMILL) — angular-sensitive electric field mills for stationary, mobile and UAV use.
• Precipitation Disdrometer (DISDROMETER01) — piezoelectric, waveform-level disdrometer for hydrometeor-type classification on moving platforms.
• Storm-resistant Anemometer (WINDGAUGE03) — Venturi-based, hail-tolerant anemometer with absolute heading via magnetometer.
• Storm measurement vehicles — integrated mobile platform combining the above instruments plus an autogyro-launch capability for in-situ thunderstorm measurements.
• Solar Patrol telescope — semi-automated solar observation assembly at Ondřejov.
• UST ionizing radiation sensors — the GEODOS / AIRDOS / SPACEDOS / LABDOS family of radiation detectors (separate site).
