Preliminary results from two low frequency Very Long Baseline Interferometry (VLBI) observations (EA009 and INTAS1) at 327 MHz are described. Sixty one sources were observed. Twenty five sources are recommended for further detailed investigation. Only two sources (3C345 and 3C309.1) could be mapped. These experiments are part of a long term pre-launch RadioAstron survey at 327 MHz that has two objectives:...
Three missions are now under consideration related to OVLBI technology: Radioastron, Millimetron and VOT.Radioastron consists of a 10-m diameter antenna and receiving complex for cm and dm ranges. This space radio telescope will operate with global network of all largest ground radio telescopes and realize angular resolution up to 30 microsecond of arc.Millimetron is the same type mission with more...
