The iMUGS Consortium, in charge of a 32,6 MEUR project developing the European standard unmanned ground system (UGS), demonstrated how defence forces can use tactical 4G/5G communications networks and UGS’ equipped with ISR and signal intelligence payloads, jammers, acoustic sensors, and various other technology to conduct missions. The demonstration that was performed in September in Latvia, was led by LMT, a member of the integrated Modular Unmanned Ground System (iMUGS) consortium, with the support of the project coordinator Milrem Robotics and featured an ensemble of different technology.
“The displayed scenarios showed that unmanned systems, enhanced with innovative communication systems and various defence technology, can be used for collecting and sharing tactical information, improve situational awareness, decrease troops physical load, and increase force protection,” explained Kuldar Väärsi, CEO of Milrem Robotics.
”For the first time ever, in a special network, a tactical network was connected with a stand-alone 5G network. This allowed communication between units and robots, as well as collecting information from sensors and placing this information into LMT’s Battle Management System “Viedsargs”,” said Ingmars Pukis, Vice President and Member of the Management Board of LMT.
Latvian National Armed Forces used two Milrem Robotics’ THeMIS Unmanned Ground Vehicles (UGV) during two scenarios to display the benefits of teaming up manned units with unmanned systems. One THeMIS UGV was equipped with an Intelligence, surveillance, and reconnaissance (ISR) payload, Signal Intelligence antenna (SIGINT) provided by The Electronic Communications Office of Latvia, Rheinmetall’s Rapid Obscuring System (ROSY) Smoke Grenade Launcher, Bittium’s Vehicular Software Defined Radios (Tough SDR Vehicular), and FN Herstal’s deFNder Light Remote Weapon Station (RWS). The RWS integration was part of the demonstration, but not of the iMUGS project itself.
The second THeMIS, used as a mule for transporting the squad’s equipment, was equipped with Rantelon’s Improvised Explosive Device (IED) Jammer and Bittium’s Tough SDR Vehicular. The units and UGVs used Bittium’s tactical communication network TAC WIN combined with LMT’s commercial 4G and a tactical 5G-SA bubble provided by Bittium and Cumucore. In addition, Krauss-Maffei Wegmann’s (KMW) Dingo infantry mobility vehicle was used as the command centre from where UGVs were operated in Line of Sight (LOS) and Beyond the Line of Sight (BLOS) mode using Bittium’s SDR radios and to where the ISR and Signal Intelligence sensor feed was relayed and incorporated into LMT’s Battle Management System Viedsargs.
Additional equipment used in the demonstration included: SRC Brasa’s NATRIX UGV used for CASEVAC, high-speed First-Person View drone, Vertical Take-off, and Landing UAV STAR, and a gunshot detection and source recognition audio sensor by Riga Technical University (RTU). The iMUGS project was launched in 2020 to develop a modular, cyber secure and scalable architecture for hybrid manned-unmanned systems. Its goal is to standardize a Europe-wide ecosystem for ground platforms, command, control and communication equipment, sensors, payloads, and algorithms. Addressed operational challenges include enhanced interoperability, increased situational awareness and faster decision-making. The system will use an existing UGV – Milrem Robotics’ THeMIS – and a specific list of payloads.
