Foreword
In 1988 the European Space Agency started with a series of studies
with the goal to prepare the geodetic user community for a dedicated
gravity field mission and stimulate cooperation among various groups.
Thereby it was left open whether the planned mission should be based on
the principle of satellite-to-satellite tracking, on satellite
gradiometry or on a combination of these two methods. In the course of
these studies it turned out that the group of the dipartimento di
ingegneria idraulica, ambientale e del rilevamento of the politecnico di
Milano and that of the faculty of geodetic engineering of the Delft
University of Technology worked much along the same line. At various
occasions very exciting and stimulating exchange of ideas took place
between these two groups. In 1991 it was therefore decided to publish
the main line of their development in gradiometry analysis, the
so-called timewise and spacewise approach, in a joint report.
Compared with the benefit it would have been rather cumbersome to try to
homogenize the adopted style of presentation and notation of the two groups.
Thus little effort was spent on this aspect. We hope that this does not
hamper reading.
The authors like to thank the European Space Agency for its support of the
CIGAR-studies and the Netherlands Geodetic Commission for publishing this
report.
