GMV demonstrates its multi-domain capabilities during REPMUS 2025 and Dynamic Messenger exercises

GMV has once again taken part in NATO’s Robotic Experimentation and Prototyping with Maritime Unmanned Systems (REPMUS) exercise and Dynamic Messenger exercise, demonstrating the company’s position as a key player for developing and deploying multi-domain technologies and technologies for autonomous systems.

The REPMUS exercise took place from September 8th to 25th in Portugal, in the areas of Tróia and Sesimbra, with GMV contributing its robust positioning, navigation, and timing (PNT) capabilities for unmanned aircraft systems (UASs).

GMV’s solution has been developed together with AERTEC as part of the AIRSENSE project, which has received funding from the European Defence Agency (EDA). The purpose of the AIRSENSE project is to develop a robust PNT system for unmanned aircraft systems, for application in GNSS-denied environments through the use of sensor fusion and artificial intelligence. The system includes jamming and spoofing detection and mitigation capabilities.

The REPMUS exercise is a periodic event organized by the Portuguese Navy, in collaboration with various Portuguese and international entities. It is considered to be one of the world’s largest exercises dedicated to unmanned vehicles in the maritime domain. It has also become one of the most important events for validating prototypes, sharing knowledge, and promoting cooperation between industry and naval forces, and this year’s event brought together more than 2,000 participants, representing the navies of various countries, industry, technology firms, academic institutions, and international organizations.

This year, the REPMUS exercise took place in parallel with the Dynamic Messenger exercise. GMV participated in that exercise as well, by contributing its solution for Coalition Shared Data (CSD) services, which had been installed on board the Spanish combat supply ship Cantabria and on one of the Portuguese Navy’s vessels, and also on a virtual platform located on the Tróia Peninsula. All of these elements were interconnected with NATO’s Maritime Component (MARCOM), to ensure effective exchanges of intelligence, surveillance, and reconnaissance (ISR) information in a coalition environment.

With its presence during both exercises, GMV is making a contribution to advancing European innovation for unmanned systems and joint ISR systems, while also demonstrating its ability to transfer advanced technological solutions into real operational environments.
