Space millimeter-wavelength very long baseline interferometry simulation software

The Strategic Priority Research Program on Space Science of the Chinese Academy of Sciences, “Space Millimeter-wavelength VLBI Array (SMVA)”, aims to build the first space millimeter-wavelength Very Long Baseline Interferometry (VLBI) array in the world. The SMVA, which has the ultra-high spatial resolution with a best of 20 micro-arcsecond that a ground-based VLBI array can not attain, is a powerful tool in imaging the hyperfine emission structure surrounding the black holes and other compact celestial objects. The simulations, such as UV coverage simulation, numerical simulation and image simulation, play a crucial role in all phases of the project, so a space VLBI simulation software was designed and implemented. This software has all the necessary and auxiliary simulation functions. And it has many advantages compared to other similar software packages: its interface is more friendly, the software package is robust and independent of operation system, the code is much easier to expand and scalable.
