In addition to the bibliographies at the end of each section we recommend the following www-sites: 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 application in national surveying. Of particular importance is the promotion of international cooperation and national coordination. 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 to 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. 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.
