A New approach to CubeSat design

Our innovative structure for CubeSat is at the heart of xU, a Swiss-made nanosatellite platform, currently available up to 3U (12U in the near future).


Assemble and disassemble your CubeSat very quickly, safely and accurately using our standardised modules (called slices). Speed-up your nano satellite development, integration and tests.


Make the structure perfectly fit the volume of your subsystems or the area of your PCBs. Modify the stiffness, the radiation shielding and the thermal conductivity. Select the position of your separation mechanisms and kill-switches.


Get rid of the old fashion PC/104-style connectors and miniaturise your design. Use Swiss cutting-edge technologies to interconnect your subsystems and build a zero-wire reliable nanosatellite.


Stack your slices and choose any size of CubeSat between 1/4U and 3U. You only have to adapt the length of the cylinders.


Remove the satellite panels and quickly access any subsystem by rotating the slices around one of the cylinders.

Open Source

The structure is and will remain open source. Rely on high-quality components and benefit from the work of others to build your nano satellite or your constellation.


CubETH is a joint project between EPFL’s Swiss Space Center and ETHZ whose main objective is to build a satellite scheduled for launch in 2016-17. The CubETH spacecraft will be capable of calculating its own altitude and position in space with unprecedented precision thus paving the way for nano-satellite constellations with inter-satellite communication capabilities. This mission will use a GNSS-based navigation information system using five patch antennas, each connected to two independent u-blox receivers. These miniaturised and low-cost receivers are able to track single-frequency code and phase data of all the major GNSS. CubETH is the first mission that officially uses ELSE xU structure.
