Command and Data Handling Products for Small Satellites

Command and data handling of small satellite missions is a fundamental part of any project. Consult the products developed by Alén Space in this area:


The brains of your small satellites and the technology needed to manage telemetry and monitor and control the satellites in a three-in-one solution.

TRISKEL is a PnP (Plug-and-Play) product with demonstrable flight legacy, which incorporates hardware and software already prepared to operate, without the need for extra configurations.

Adaptable to different types of space missions, this solution integrates in one product the telemetry and command systems, the technology needed to allow the monitoring of the satellite from the ground and the control of its operations in orbit.

The configuration of the TRISKEL software also allows perfect communication with the Mission Control Software (MCS) located on the ground.

What does TRISKEL include?

  • On-board Computer (OBC).
  • Telemetry, Tracking, and Command (TTC).
  • On-board software (OBSW). Based on the ESA Packet Utilization Standard (PUS), it provides meticulous control of the satellite: error detection and repair, recovery system, TOTEM payload on/off, parameter setting, antenna control, etc.


TOTEM DVB-S2 is an ideal solution for missions with S-band small satellites, which require the transmission of large files or the download of data at high speed, up to 2 Mbps.

Alén Space’s DVB-S2 solution allows high data rate communications, so you can maximize the download of information and shorten the time needed to receive the data generated by the payload of small satellites.

This product is based on our experience of more than 12 years in the development of TOTEM, our SDR platform for small satellites successfully tested in space.
