Introduction to VLBI

1989
The principles of Very Long Baseline Interferometry are essentially the same as those in connected-element interferometry. Both systems can be used to make images of extended radio sources through the application of various calibration and image restoration techniques or to measure geometric quantities such as the positions of point sources or baseline

Future directions of space VLBI: International VLBI Satellite (IVS)

Advances in Space Research, 1991
Abstract Future space VLBI missions will explore new dimensions in angular resolution, sensitivity, frequency range and image quality. The International VLBI Satellite (IVS), currently under assessment by ESA and the Soviet Academy of Sciences, proposes to make significant advances in all these parameters compared with the first generation missions ...

Progress in VLBI at Shanghai Observatory

1988 Conference on Precision Electromagnetic Measurements, 1988
An overview is presented of recent developments on very-long-baseline interferometry (VLBI) at the Shanghai Observatory. The Shanghai Radio Station, which is equipped with a 25-m antenna, and other facilities that became operational in 1988, are described. The VLBI data-processing system is discussed. It includes an S-2 VLBI data processor and a series
