Method for Determining the Parameters of a Ring-like Structure from the Visibility Function Shape
S. V. Chernov, M. A. Shchurov, I. I. Bulygin +1
Black hole images obtained by very long baseline interferometry (VLBI) by the Event Horizon Telescope are a new tool for testing general relativity in super-strong gravitational fi…
Orbit Design for the Millimetron Space Observatory
T. A. Syachina, A. G. Rudnitskiy, P. V. Mzhelskiy +2
Millimetron is a space observatory for millimeter and sub-millimeter observations planned for launch around 2030. The 10-meter diameter space unfolded telescope will be cooled down…
Estimation of Orbital Parameters from (u,v)-coverage for a Space Radio Interferometer
I. I. Bulygin, M. A. Shchurov, A. G. Rudnitskiy
Finding a suitable very long baseline (VLBI) interferometer geometry is a key task in planning observations, especially imaging sessions. The main characteristic of the quality of…
On Optimal Geometry for Space Interferometers
A. G. Rudnitskiy, M. A. Shchurov, S. V. Chernov +2
This paper examines options for orbit configurations for a space interferometer. In contrast to previously presented concepts for space very long baseline interferometry, we propos…
Processing System for Coherent Dedispersion of Pulsar Radio Emission
Girin I. A., Likhachev S. F., Andrianov A. S. +5
The work describes a system for converting VLBI observation data using the algorithms of coherent dedispersion and compensation of two-bit signal sampling. Coherent dedispersion is…
Analysis of Orbital Configurations for Millimetron Space Observatory
A. G. Rudnitskiy, P. V. Mzhelskiy, M. A. Shchurov +2
In this contribution a primary feasibility study of different orbital configurations for Millimetron space observatory is presented. Priority factors and limitations were considere…
RadioAstron orbit determination and evaluation of its results using correlation of space-VLBI observations
M. V. Zakhvatkin, A. S. Andrianov, V. Yu. Avdeev +14
A crucial part of a space mission for very-long baseline interferometery (VLBI), which is the technique capable of providing the highest resolution images in astronomy, is orbit de…
Software correlator for Radioastron mission
S. F. Likhachev, V. I. Kostenko, I. A. Girin +3
In this paper we discuss the characteristics and operation of Astro Space Center (ASC) software FX correlator that is an important component of space-ground interferometer for Radi…
