QB50 satellites apply for frequency coordination

Typical QB50 CubeSatThe first CubeSats of the planned QB50 satellite constellation have applied to the IARU for frequency coordination.

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
