The Vaisala Radiotheodolite RT20 is an integral part of automated meteorological data acquisition for mobile field artillery and other land-based tactical defense units. The RT20 is an advanced, all-weather interferometric RDF antenna that meets all the operational requirements of tactical field units. It consists of man-portable modules which can be integrated easily into your own mechanized transportation concept.

The Vaisala Radiotheodolite RT20, as a part of the complete tactical Vaisala sounding system including 1680 MHz Vaisala radiosondes, provides highly accurate upper-air meteorological data (wind speed/direction, humidity, temperature and pressure) in standard message formats. Easy to transport and quick to deploy, the RT20 has proven to be the world’s most advanced and accurate RDF antenna for upper-air sounding. Alongside the RT20, the ruggedized Vaisala DigiCORA® Sounding System MW21 automates data handling and message transmission through the full range of telecommunications interfaces.
