A method for calculating strain field from repeated GPS observations is presented. It includes three major procedures. At first, the adjustment of a GPS baseline network is carried out. Both the displacements of observation points and the variations of base-, lines in the network are calculated out in this procedure. And then, the whole network is divided into finite uniform grids. The displacements on the grid points are calculated by using an interpolation and extrapolation method. Finally, The principal strains and dilatation in each grid area are calculated from the displacements on its grid points by assuming a uniform strain field within the small grid area. As an example, the strain field in the Sagami Bay from 1989 to 1990 has been calculated.
