Abstract

Three satellite missions CHAMP, GRACE and GOCE are defining primary goals of research in geosciences in this decade. Subjects of CHAMP-mission are Earth gravity and magnetic field and measurements of the Earth atmosphere parameters. CHAMP-mission is making SST-measurements for modeling of the gravity field. They are corrected for non-gravitational perturbations using accelerometer measurements. The quality of these measurements is defining new standards of modeling of the Earth gravity field. CHAMP-magnetometry is giving opportunity to obtain models of main magnetic field, magnetic influence of Earth's crust and better separation of weak magnetic signals. CHAMP GPS-radio occultation measurements are giving new possibilities in collecting meteorological parameters. CHAMP is initializing new interdisciplinary researches of structure and dynamic of the Earth's interior, research of the influence between ocean and atmosphere (geosphere), more reliable monitoring of the oceans circulation, global changes of the sea level, short periodic global water circulations, changes of the weather and climate (hydrosphere) and global atmosphere sounding that is giving better meteorological relations on the Earth (atmosphere). Results of CHAMP-mission already gave new knowledge about geosystem and defining new standards in solving scientific and practical problems in more branches.
