The aim can to be achieved by setting up a global network of underground antennas, each equipped with a manifold of small-sized, direction-sensitive antineutrino detector systems. The precise shape and location of these antennas will evolve as direction-sensitive detector systems are developed. One of the options is to investigate an antenna concept in which the detectors will be placed in a shallow underground laboratory. Combining the results of the global network of antennas will produce a tomographic image of the location and the extent of antineutrino emitting heat sources. It is expected that the global network will reach a resolution of about 3, corresponding to a resolution of about 300km at the centre of the Earth or 150km at the core-mantle boundary. From the energy of the antineutrinos a deduction can be made on the type of source emitting the antineutrinos.
