SATELLITE PLATFORMS

Small Satellite Platforms

The platforms developed by Alén Space reflect the extensive experience of our team in the manufacture of small satellites (nanosatellites and microsatellites) under the CubeSat standard.

Platform Comparison Chart

Alén Space offers you five small satellite platforms (1U, 2U, 3U, 6U and 12U) already prepared to integrate in record time with the payload you have selected or developed for your project. All buses include structure, solar panels, on-board computer, antennas, batteries and communication systems, power and attitude control (ADCS).

Our small satellite platforms have been developed with high quality processes and under the same technical standards. This means that you can manage and operate your satellites in a single way, regardless of their size.

Training Satellites

Alén Space has training satellites that fit perfectly with the needs of universities, technology centres and other organisations and companies that want to start developing their own capabilities in the manufacture of CubeSats:

Kit Satellite

Get all the components and parts to assemble a fully functional satellite. With our Kit Satellite you will receive one of our platforms so you can take care of its assembly in-house, with your own equipment.

Flat-sats

Our satellite models replicate all the details and parts that make up a CubeSat. For functionality and price, the flat-sats are an ideal solution for training tasks of learning the process of building small satellites.
