What is Argos?

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

Since 1978, Argos has responded to the needs of the world’s scien- © JAMSTEC tific and industrial communities. Argos gives scientists a tool to Argos is used to observe the oceans and understand climate change. enhance their understanding of our environment and helps industry comply with environmental protection regulations. Today, over 16,000 Argos transmitters are active each month worldwide.

Argos is used by scientists, governments, industry and international organizations. To meet the sys- tem use requirements, all programs using Argos have to be related to environmental protection, awareness, study, or protecting human life. Applications for which a clear governmental interest prevails are also approved.

Tracking Scientists use Argos to track animals and study their behavior.

Argos tracks any mobile platform fitted with an Argos transmitter for scientists and govern- ments. The positions collected can be used for many applications, including monitoring the route of a fishing vessel, following large migra- tions of birds and other animals, or mapping ocean currents by tracing oceanographic buoy drifts. Argos is used to monitor freshwater resources.

Monitoring

Argos provides environmental monitoring from remote platforms, either fixed or mobile, fitted with an Argos transmitter. Sensors on Argos platforms collect data on atmospheric pres- sure, sea temperature, animal heart rates and

water level, for example. Governments use Argos to track fishing vessels in their Exclusive Economic Zone.

Users program their transmitters and choose adequate sensors for the type of observations they need. These observations are especially important for creating comprehensive global data sets that are used by people working together around the world on the same or similar topics.

Health ministries use Argos terminals to relay information on epidemics from remote areas. argos applications What does Argos do?

Improving ocean and weather information and forecasting

In addition to climate research, oceanogra- phers and meteorologists also use Argos to gather in situ observations for operational oceanography and meteorology. Argos buoys, floats and fixed stations collect data for opera- tional programs such as World Weather Watch (WWW). Over 70 percent of Argos data are exchanged on a global and voluntary basis for insertion into numerical ocean and weather prediction models via Global Telecommunication System (GTS). Furthermore, Argos offers ocean data telemetry services for a broad spectrum of applications including ocean modeling, moored buoy monitoring and more. > 2 Protecting biodiversity >3 argos applications What does Argos do?

The future of our fisheries depends to a large extent on our ability to preserve stocks effec- tively. As a result, most coastal nations now mandate fishing vessels operating within their Exclusive Economic Zone (EEZ) to be equipped with a satellite-based vessel monitoring sys- tem (VMS). Argos provides a global solution, ArgoNet, which meets the requirement for monitoring fishing vessels and their catches.

The trustworthy Argos transmitter sends fully automatic signals at regular intervals, tracking the exact progress of expeditions and reassuring the adventurers’ family and base. Similarly, yacht racers count on the robustness of Argos to track their boats as they whip around the globe through treacherous waters.
