QB50 has the scientific objective to study in situ the temporal and spatial variations of a number of key constituents and parameters in the lower thermosphere (90-320 km) with a network of about 40 double and 10 triple CubeSats. These, university built, CubeSats will be launched into a 320 km circular orbit, will be separated by a few hundred kilometres and carry identical science sensors.
The sensors will monitor parameters that will greatly increase our knowledge and understanding of this little explored region of the E and F layers of the Ionosphere. QB50 will also study the re-entry process by measuring a number of key parameters during re-entry and by comparing predicted and actual CubeSat trajectories and orbital lifetimes.
Some of the first CubeSats to apply for frequency coordination are SUSat, Hoopoe/IL01, SAT-IP2, ExAlta-1, OGMS-SA, InflateSail, XCubesat, SpaceCube, UNSA-SAT1, EntrySat, PHOENIX and Dragsat-CubeSat, see http://www.amsatuk.me.uk/iaru/formal.php
