Using Argos

Argos provides worldwide long-distance tracking and monitoring from any mobile or fixed station fitted with an Argos transmitter.

Argos is a unique worldwide location and data collection system dedicated to studying and protecting the environment.

Information is relayed via the Argos satellite system and is used for numerous applications ranging from ocean observations, wildlife protection to fisheries monitoring and maritime security


Argos tracks any moving station fitted with an Argos transmitter for scientists and governments. Several positions collected over a fixed period of time can be used to monitor the route of a fishing vessel, large migrations of birds and other animalsoceanographic drifting buoys and their route through the ocean based on currents… and many other applications. Trajectories (or tracking data) are made available via a specially designed website, where they are displayed on maps, in tables or charts. They can also be received automatically by email, directly through mapping software, fax or cd-rom.

Archival tag data processing

Internal and pop-up satellite transmitting archival tags deliver essential information on the migration patterns, habitats and underwater behavior of marine fish. They usually rely on lightbased geolocation, yet location often remains inaccurate, with errors of several degrees. In collaboration with the scientific community, CLS has actively contributed to the improvement of light-based geolocation, and now offers  archival data processing services .This service is particularly suited for fisheries scientists and field biologists who prefer to focus on the ecological interpretation of tag results rather than on the technicalities of tag data processing.

Optimizing Argos tracks via Kalman reprocessing and/or Earth observation data

CLS provides a number of value-added services to enrich your Argos tracks. Reprocess your Argos data (from 2008 to present) using our multiple-model smoothing technique or enhance your trajectories with weather and ocean data.

CLS operations center


Argos provides environmental monitoring from remote stations, either fixed or mobile, fitted with an Argos transmitter. Sensors on Argos platforms collect data on atmospheric pressuresea temperatureanimal heart ratesalarm management or water level of a river, for example. Users program their transmitters and choose adequate sensors for the type of observations they need. Collecting observations is especially useful in creating comprehensive global data sets that are used by people working together around the world on the same or similar topics. As with tracking, data is made available via a website or sent to users automatically.
