From Mars to Greenland: Charting Gravity With Space and Airborne Instruments

Presents the results of an investigation of space and airborne methods for gravity measurement using satellites over Greenland. The contributors discuss computational methods and describe the different techniques, such as the airborne measurement of gravity and satellite gradiometry.

Precise and continuous tracking with multi-satellite systems of aircraft and low flying satellites, accurate airborne measurement of gravity and gravity gradients, and satellite gradiometry have fundamentally changed our view on the de- termination of the Earth's gravity field. The papers in this volume describe these techniques in detail. The ideas are presented as complementary, and are used to develop new theoretical concepts of gravity field analysis. Computatio- nal models using these techniques are also discussed and are tested in simulations. The papers presented in this volume are the result of an IAG symposium held during the XX General Assembly of the Inter- national Union of Geodesy and Geophysics in Vienna, Austria, August 11-24, 1991.
