Data Collection Systems

Iridium logo

Iridium® is the world’s largest commercial satellite constellation providing global mobile satellite communications, including voice and data solutions.

The Iridium® System is a satellite-based wireless communications network providing a robust suite of data services virtually anywhere on Earth. Its three principal components are: the satellite network, the ground network and the Iridium subscriber products. It provides two-way communications and is used by our TRITON VMS and PILOT transmitters. CLS has been a certified Iridium® VAR since 2007.

Argos logo

Argos is a unique data collection and satellite location system, well-known as a worldwide system for observation. It offers one-way data transmission.

Argos is operated and managed worldwide by CLS Group. Several other international agencies also actively participate in the Argos system, including: French Space Agency (CNES), National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), Eumetsat (European Organization of the Exploitation of Meterological Satellites), Indian Space Research Organization (ISRO)


  • Global coverage
  • Reliable
  • Robust in harsh conditions
  • Low power consumption
  • Low cost for modem & antennas
Kineis Logo

Capitalizing on our long experience in state-of-the-art, innovative instrumentation, along with the French Space Agency CNES, CLS invested in a new generation of Argos payloads, called Argos-4, that will fly on the satellites of international partners starting in 2020. The increased bandwidth of Argos-4 as well as the operational downlink will make it possible to send ever more data even more efficiently, improving performance for existing applications as well as opening the door for a host of new ones.

At the same time, CLS, with the support of the French Space Agency CNES, is working to develop a completely new generation of 25 nanosatellites. This constellation, managed by our spin-off company, Kinéis, will be fully operational in 2022.


  • Low-cost global coverage
  • Two-way transmission
  • Low power consumption
  • 25 nano-satellites
  • Shorter revisit time
  • 8X more bandwith
