Both satellites would have been launched by a single Scout-F1 launch vehicle into coplanar polar orbits. Measurements of atmospheric density from DAD-A would have been obtained from satellite drag analyses near perigee (approximately 350 km) and from composition measurements taken by an onboard mass spectrometer. DAD-A was equipped with a radio beacon to facilitate tracking.
