A magnetometer array may be regarded as a telescope allowing imaging of magnetospheric dynamics in the ulta low frequency, near DC range of the electromagnetic spectrum. The field of view of such an array lies in the range of several thousand km depending on the array's size. The resolution is typically of the order of 50 to 100 km in the ionosphere, i.e., 1500 to 300 km in the magnetosphere. Highly sophisticated image processing tools were developed which make magnetometer arrays a very important tool to complement in situ measurements such as planned for the Cluster project. One of the aims of this project is the study of small scale plasma processes in, for example, the dayside polar cusp region. As the archipelago of Svalbard (Arctic) lies within the region of the northern polar cusp the installation of an international magnetometer array on Spitsbergen is strongly suggested.
