PREFACE

The Swiss Geodetic Commission (SGC) is an organisation within the Swiss Academy of Sciences
(SCNAT). It is devoted to research into scientific problems of geodesy including the transfer to
practical applications in national surveying. Of particular importance is the promotion of international
cooperation and national coordination. The SGC has close links to the Swiss Geophysical
Commission, in particular in the field of gravimetry where research projects are being pursued jointly
on an interdisciplinary basis.

For the compilation of the national report covering the scientific activities of the past 4 years it was
decided to follow the structure of previous national reports and divide it into 4 commissions according
to the structure of the International Association of Geodesy (IAG):

1 Reference Frames
2 Gravity Field
3 Earth Rotation and Geodynamics
4 Positioning & Applications

These main chapters were compiled by an editorial staff consisting of A. Wiget (Commission 1), U.
Marti (Commission 2), M. Rothacher (Commission 3), P.-Y. Gilliéron (Commission 4). Our special
thanks go to J. Mueller-Gantenbein, secretary of SGC, for the careful editing and preparation of the
layout. Without her efforts this report could not have been realized in due time.

The SGC expresses its appreciative thanks to all colleagues who have contributed to this report and
who are promoting Geodetic Sciences in Switzerland. Financial support was provided by the SCNAT.
Its valuable help is gratefully acknowledged.

On behalf of the Swiss Geodetic Commission, June 2015
