DESCRIPTION:Speakers: Dr. RUDNITSKIY\, Alexey (ASC LPI)\nThe “Radioastro
 n” space mission is the unique project of Russian Space Agency (Roscosmo
 s) and Russian Academy of Sciences to investigate the Universe by means VL
 BI principles implementation with “Spektr-R” space satellite. “Spekt
 r-R” onboard 10-m radio telescope has been operating since 15 November\,
  2011 as the Space element of the space-ground interferometer at the orbit
  with its apogee up to 350000 km. The first and the basic step in VLBI obs
 ervations data processing is correlation. Space-VLBI brings new requiremen
 ts in correlation process due to significant uncertainties in delay model 
 for space telescope. Radioastron mission correlator is a part of ASL (Astr
 o Space Locator) software package for Windows environment developed in Ast
 ro Space Center (ASC) of Lebedev Physical Institute. In this report the ma
 in features and operational procedures of the ASC Correlator are described
  with the emphasis on the Space-VLBI data-processing differences compared 
 to the ground VLBI. \nAlso\, a description of time delay and its derivativ
 es calculation algorithm is presented in this report\, as well as the proc
 edure of correction for these parameters. This approach is critical for th
 e correlation of space-ground interferometer data. In this report we also 
 show the importance of the orbit accuracy and correlator requirements for 
 the future Space-VLBI missions\, such as the “Millimetron” project.\n\
