Numerical optimisation of constellation and orbit design for the OLFAR radio interferometry swarm in orbit of the Earth-Moon L4 point

In the field of radio astronomy the Ultra-Long Wavelength (f < 30MHz) band is unique, it has been studied for nearly a century yet it is still almost completely uncharted. Due to the reflective properties of Earth's ionosphere this band is nearly completely inaccessible for ground-based observatories, which can only receive frequencies down...
