Book Description
VLBI is an acronym for Very Long Baseline Inferometry, and can be roughly divided into two areas of application. The first area is in geodesy, which is covered in considerable detail in this book. The second area is in astrometry, or radio astronomy, which is only briefly treated in the book.

Book Description
The quest for high resolution has preoccupied radio astronomers ever since radio waves were first detected from space fifty years ago. This venture was par ticularly stimulated by the discovery of quasars, and led to the development of interferometer techniques using baselines of transglobal dimensions. These meth ods have become known as Very Long Baseline Interferometry (VLBI). Arrays of radio telescopes situated all over the Earth (or even in space) are regularly used for researches in radio astronomy, reaching resolutions as small as a fraction of a milli arcsecond. The technique also allows the measurement of the positions of the radio telescopes to a few millimeters and so VLBI has become a major tool in geodesy and the study of the rotation of the Earth. VLBI has now passed the pioneer stage and is becoming a standard facility available to astronomers and geodesists, requiring the coordination of the operations of indpendently owned radio telescopes around the world. In Europe observatories from England, Federal Republic of Germany, France, Italy, Poland, Sweden and The Netherlands are coordinated in their VLBI activity by the European VLBI Network Consortium (EVN). The Programme Committee of the EVN allocates time to scientific projects on a routine basis three times a year. The Unites States has a similar arrangement of a network of independent radio observatories, and joint experiments using 'Global Network' are often made.

Book Description
High-precision astrometry has a long history of making fundamental contributions to geodesy and geophysics extending centuries into the past, and has provided the foundation for many exciting developments in geophysics in the last several decades. In the 1970s, geodetic Very Long Baseline Interferometry (VLBI) and laser ranging provided the first direct measurement of plate tectonic deformation of the crust. These techniques also have revolutionized the study of Earth rotation by providing sufficient precision to measure climate variability, internal structure, and physical properties. Astrometry will continue to be important in a variety of geophysical problems because of its unique ability to determine Earth orientation relative to a stable celestial frame. Sections discuss the following: astrometric contributions to geodesy, the International Terrestrial Reference Frame, earth orientation changes, improved tidal models, contributions to geophysics, the solid Earth, and the climate.
