Argos Platforms

Argos is adapted to a wide range of applications

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

A wide selection of Argos platforms exist and CLS can help choose the transmitter that fits your needs


Argos goniometer : Argos Direction Finder for Recovery & Tracking

The CLS goniometer helps users find active ARGOS platforms in the field.Depending on the altitude and the reception conditions the goniometer can detect all transmitting platforms within a radius of 100 km or more.

Argos transmitters to track animals

Argos transmitters provide an accurate means of monitoring wildlife through all types of habitats and climates. There are a variety of transmitters for land animals, marine animals and birds that are ideally suited for migration and habitat studies. There are diffrent types of products : ideally suited to wildlife behaviour and habitat utilization studies, including fin tag and glue-on attachment for marine applications or reducing one (small than 5 gr) for birds…

Wildlife monitoring

Drifting buoys

Drifting buoys provide operational, near-real time surface velocity, sea surface temperature (SST) and sea level pressure observations for numerical weather forecasting, research, and in-situ calibration/verification of satellite observations. Drifting buoys are generally attached to some form of drogue or sea-anchor, are easy to deploy, are relatively inexpensive to operate and reliably measure the atmosphere and ocean surface conditions, for an average of 18 months.


Ice buoys

Ice buoys can measure a variety of oceanographic and meteorological data which are relayed through the ARGOS satellite system. Ice buoys have been used extensively in Arctic and Antarctic regions to track ice movement and are available commercially for deployment by ships or aircraft. Such buoys are equipped with low temperature electronics and lithium batteries that can operate at temperatures down to -50°C.


Moored buoys

Moored buoys are normally relatively large and expensive platforms. They can vary from a few meters in height and breadth, to over 12 meters. Measurements from the mooring include surface variables : wind, air and sea surface temperature, salinity, air pressure, as well as subsurface temperatures down to a depth of 500 plus meters.


Subsurface floats

Subsurface floats or argos profiling float are gathering data at mid-depth and surfacing from time to time to transmit. These platforms are coordinated under the Argo program led by JCOMMOPS which is an international collaboration that collects high-quality temperature and salinity profiles from the upper 2000m of the ice-free global ocean and currents from intermediate depths.


Fishing vessels

CLS provides an Argos-based satellite terminal to track Fishing vessels. CLS also develops fleet-tracking software that can be combined with ocean data that will help operators analyze their fleet’s operations. A range of beacons designed to track fishing vessels by satellite within the framework of a vessel monitoring program (VMS).

Boat Races

Over the last 20 years and more, CLS has already equipped tens of thousands of navigators. Sailing and rowing boats are equipped with reliable, shock-proof, hardened beacons, fully adapted to marine conditions and are monitored on all the oceans on our planet. A team of operators and system engineers permanently monitor the messages transmitted by the beacons. Both request for assistance to the race management and Man Over Board functions of the beacon improve the safety of skippers and adventurers.

Maritime security


Offshore equipment like moored buoys and subsurface moorings are expenssive assets that contain valuable datasets. Deployed in the high seas, they are exposed to a rough environment, potential theft and constitue a navigational hazard. It is crucial to be warned in case of incident and to recover this valuable equipment as quickly as possible.
