DTU requires IPcores library for the LISA PMS Mission. The Ipcores will be used in the phaseme-ters that will be a essential part of LISA – the Laser Interferometer Space Antenna - which will be the first dedicated space-based gravitational wave observatory. Gravitational waves are ripples in the fabric space-time created by suitably accelerated objects, such as pairs of black holes coming together and merging. The mission will comprise three spacecraft flying in a triangular formation behind the Earth as our planet orbits the Sun.
