NetSat is to demonstrate for the first time the self-organization of several satellites in three-dimensional space within the framework of a formation in orbit. To this end, important new technologies for formation control and coordination are being researched. This will then open up innovative perspectives for future sensor networks in space for Earth observation, such as three-dimensional images of the Earth’s surface and computer tomography methods for looking inside clouds.

Prof. Dr. Klaus Schilling (Univ. Würzburg) received this highest valued European research award for individual scientists from the European Research Council in 2012 and realized this pioneering research at ZfT as host institution, owing to its outstanding test environment for multi-satellite systems.
The in-orbit formation tests were also funded by the Bavarian State Ministry of Economic Affairs, Regional Development and Energy as part of the ForTe project.
As part of NetSat, four Cubesats (with a mass of only 4 kg) were developed with the necessary miniaturized subsystems to allow operations in the form of a self-organizing formation; examples include advanced systems for attitude determination and control, orbit determination, telecommunication, electrical propulsion for orbit control and formation maintenance, in particular also distributed, adaptive control systems related to self-organisation in orbit. This mission realizes, for the first time worldwide, a formation flight of satellites in a three-dimensional configuration. This enables potential innovative future applications in Earth observation.
The four NetSat satellites were placed in a low-earth orbit by a Soyuz rocket on September 28, 2020. Further information about the rocket launch and the livestream can be found here: NetSat Launch Event.
