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

VLBI, GPS and Greenhouse

Australian Surveyor, 1992
Abstract One impact that mankind has inflicted on the environment has been an increase in the amount of greenhouse gases present in the atmosphere. A likely result of this is an increase in average global temperature and rise in sea level. In order to monitor this rise over the coming decades, an international programme of geodetic measurements using ...
