The most sensitive VLBI array in the world is the European VLBI Network (EVN). This is a part-time array that brings together the largest European radiotelescopes and some others outside of Europe for typically weeklong sessions, with the data being processed at the Joint Institute for VLBI in Europe (JIVE).
The Chinese Deep Space Network (CDSN) is a network of large antennas and communication facilities that are used for radio astronomy, radar observations, and spacecraft missions of China. The CDSN is managed by the China Satellite Launch and Tracking Control Center General (CLTC) of the People's Liberation Army Strategic Support Force Space ...
The position is determined using a combination of the so-called Unified S-Band Technology (USB), where the distance and speed of the satellite are calculated from the Doppler shift of the carrier wave for the telemetry signals, and long-base interferometry, where connected radio telescopes are using the Chinese VLBI network to determine the ...
European VLBI Network (EVN) Distributed across Europe with members in China, South Africa and the US VLBI array operated by the European Consortium for VLBI: Plateau de Bure Interferometer: Plateau de Bure, Grenoble, France Originally an array of 3 antennas, since 2005 has 6 antennas, operating at millimeter wavelengths, now part of NOEMA
The main goals of the QTT include imaging of pulsars, stellar formation, and the large-scale radio structure of the universe. [7] [4] Other goals are the use of Pulsar Timing Arrays to detect nanoHertz gravitational waves, to be part of Very Long Baseline Interferometry, to study the interstellar medium, to study galaxies and black holes, to study dark matter and to carry out astrometry.
It was formed in 1962 from the merger of the Xujiahui (also romanized as "Ziikawei") and Sheshan (Zose) observatories in Shanghai. It was involved with the Chang'e 1 Moon mission as the VLBI array is used for position determinations. In October 2012 the Tian Ma 65-meter (213 ft) radio telescope was completed for SHAO. [1]
Ye Shuhua (Chinese: 叶叔华; born June 21, 1927) is a Chinese astronomer and professor at Shanghai Astronomical Observatory, known for achieving one of the world's most precise measurements of Universal Time in the 1960s, and for establishing the very-long-baseline interferometry (VLBI) and satellite laser ranging (SLR) techniques in China.
The European VLBI Network (EVN) is a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa and Puerto Rico, which performs very high angular resolution observations of cosmic radio sources using very-long-baseline interferometry (VLBI). The EVN is the most sensitive VLBI array in the world ...
