context_page_description: Tamara was the third generation Czechoslovak electronic support measures system that used measurements of time difference of arrival of pulses at three or four sites to accurately detect and track airborne emitters by multilateration. Tamara's designations were KRTP-86 and KRTP-91 and it carried the NATO reporting name of Trash Can. The designation was derived from the Czech phrase "Komplet Radiotechnického Průzkumu" meaning "Radiotechnical Reconnaissance Set". It was claimed to be the only one in the world able to detect military "invisible aircraft".
context_section_description: Development of Tamara by the state-run company Tesla in Pardubice began in 1981 and continued until 1983. Tests of a mobile system began in September 1984 through to 1985. It was finally deployed in 1987 following acceptance tests in October of that year.  In 1991 the baseline KRTP-86 Tamara was superseded in production by improved the KRTP-91 Tamara-M.
