Argos Today & Tomorrow

Created by CLS and the CNES, Kinéis, as the new operator of the Argos system, benefits from 40 years of experience that provides easy and global access to satellite data.

As historical operator of the system, CLS works in close collaboration with Kinéis and remains a dedicated Value-Added Reseller (VAR) for a variety of applications dedicated to understanding and preserving the environment, biodiversity and life.

In 2024, Kinéis will launch 25 nanosatellites on 5 different orbits thereby upgrading the system and offering users unprecedented capabilities:

  • Capacity to connect 2 million transmitters
  • Optimized reception quality enabling trackers to be smaller and consume less energy
  • 15-minute revisit time
  • Two-way capabilities

Hardware such chipsets and low power transmitter modules means connecting devices to the Argos system is even easier.

How does Argos work?

Polar orbiting satellites collect data by picking up the signals from platforms integrating Argos-certifed transmitters.

These signals, or messages are stored onboard the satellites and transmitted to dedicated recieving stations.

The network pf ground stations forwards the messages to an operations center, where it is processed, stored and automatically delivered to users through a web interface, API or even directly via email.
