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 and is used by our VELA and MARGE V3 VMS transmitters.

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

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
