Radio Solar Telescope Network Radio Solar Telescope Network The Radio Solar Telescope Network (RSTN) is a network of solar observatories maintained and operated by the 557th Weather Wing, ACC. The RSTN consists of ground-based observatories in Australia, Italy, Massachusetts, New Mexico and Hawaii. It became apparent in the early 1960s that certain space weather events might interfere with the stated U.S. objective of a manned mission to the moon. In particular, the sun emits continuous electromagnetic energy and electrically charged particles, which can cause disturbances in the near-Earth environment and disrupt satellite communications. Foremost among these concerns was the possibility of a geomagnetic storm
Giant Ukrainian Radio Telescope subarrays is successive, spanning over a period of time, as resources become available. With increase of number of subarrays and effective area the number of astrophysical problems to be solved by GURT will increase significantly. Joint simultaneous observations of radio astronomical sources with many instruments all over the world are very important at low frequencies due to many hindering factors. Various RFI conditions, different impact of ionosphere at the site of radio telescope, various configurations and parameters of distant radio telescopes increase significantly the informativity of received signals.
