The td-1a satellite, designed to carry a payload of seven experiments into a near-polar orbit in spring, 1972, is esro's largest spacecraft to date and its first satellite with a 3-axis stabilisation system. the experiments are aimed at stellar ultraviolet spectroscopy and solar and cosmic ray radiation. Orbital and attitude control characteristics are chosen such that the sky-pointing experiments will scan the complete celestical sphere within six months.
