Since the One Planet, Didac Costa has dropped an ECHO buoy, as well as an Argonautica buoy, on January 14, 2017 near the point NEMO, the point of the ocean furthest from any earth.

During each edition, skippers embark Argonautica beacons whose drift is followed by the Argos satellite system and the data are used by CNES partner schools to study the marine environment. The Argos system is a global system for locating and collecting data by satellite. It allows to locate the tags anywhere on the surface of the Earth. These tags can be installed on a sailboat, buoys, as on animals. The Argos system collects data transmitted by Platform Transmitters Terminals (PTTs) and distributes sensor data and location information to the end users. Operated by CLS, the Argos system not only helps the scientific community to better monitor and understand our environment, but it also enables manufacturers to comply with regulations set by several governments for environmental protection.

With ECHO buoys, developed in part by students and high school students to test innovative energy sources, an innovative idea is set up. The first prototypes, dropped during the Vendée Globe 2016, were made by Tenum, a company specializing in telemetry and digital radio transmission. Before proceeding with the development of the energy solution, these prototypes equipped with alkaline batteries will make it possible to check the leak tightness of the beacon and the correct operation of telemetry to locate them. A test in real conditions, in the currents and waves of the great South!
