Teltronic Supplies TETRA/LTE System for Antarctica Research

Teltronic deployed what it called the first TETRA and Long Term Evolution (LTE) convergent radio communications system in the world. The company completed this milestone in Antarctica, with equipment that had to endure the most extreme weather and environmental conditions.

The deployment, using a single network management system and control node for both accesses, was developed within the framework of the Galileo Public Regulated Service (PRS) project of the General Directorate of Armament and Material and the Navy in Antarctica, which the Spanish Ministry of Defense commissioned to the technological multinational GMV to perform a demonstrator that validates safe satellite navigation. Researchers are testing the concept of PRS signals of Galileo, the European satellite radio navigation and positioning program developed by the European Union jointly with the European Space Agency.

All the tests of the research project were made last year during the annual expedition that the Spanish Navy’s oceanographic research ship Hespérides carries out to the Antarctic continent. To develop the project tests, a robust communications system with voice and broadband data transmission capacities was required to allow not only communications among staff members but also the massive and real-time data transmission from systems installed on land to the control center and databases installed on the ship.

The encrypted and controlled-access communications solution selected was a hybrid convergent TETRA and LTE system, and Teltronic was responsible for deploying it onboard the Hespérides, which sailed within a radius of 5 kilometers from the work zone both on land and an auxiliary vessel. The PRS satellite signal receiver, together with a TETRA-LTE dual terminal, were placed onboard the ship.

Teltronic installed a complete solution based on its eNEBULA communications infrastructure, including the central node that provides intelligence to the network, the base stations cover the operation area and the dual communication terminals.

The LTE access allows the transmission of the positioning data that is sent from the Galileo to be received on the ground by the PRS receiver to the Hesperides. In addition, TETRA technology serves to support voice communications in which the research staff and crew members participate.

This experience means an important milestone for the evolution of critical communications in professional environments, with TETRA as a reference standard and LTE as a logical evolution toward broadband applications but always maintaining the rigorous requirements in terms of availability and security demanded by environments such as this project.

Hespérides is the only Spanish vessel designed to conduct multidisciplinary scientific research in all the seas and oceans of the planet, including the Arctic and Antarctic zones. The main activity of the ship focuses on the southern summers, during which it conducts scientific campaigns in Antarctica. The rest of the year its activity extends to all the oceans and seas, mainly Atlantic, Pacific and Mediterranean, providing support to all types of scientific campaigns.
