Project Description
CHAMP (Challenging Mini-Satellite Payload for Geo-scientific Research
and Applications program) will perform the following three tasks: 1)
Mapping of the Earth's global long to medium wavelength gravity field
and temporal variations with applications in the geophysics, geodesy
and oceanography; 2) Mapping of the Earth's global magnetic field and
temporal variations with applications in geophysics and solar
terrestrial physics; 3) Atmosphere/ionosphere sounding with
applications in global climate studies, weather forecasting, disaster
research and navigation. This is a cooperative project with
Germany. Energy forecasting and water management.
