Indra announced that it has completed the development and certification tests of its new satellite communication terminal, the TSUB-40Ka, designed for submarine platforms. The new system has been engineered to meet the operational needs of modern submarines, offering a more compact structure and higher data transmission speeds.
Unlike traditional X and Ku bands, the TSUB-40Ka uses Ka-band technology, enabling broadband communication on space-constrained platforms such as submarines. This allows the use of smaller antennas while increasing data transmission rates. In addition, the terminal combines the durability required by military standards (MIL-STD/STANAG) with advanced connectivity capabilities.
SpainSat NG Integration and Security
The TSUB-40Ka terminal has been certified by HISDESAT to operate in compatibility with the SpainSat NG system, which incorporates X, military Ka, and UHF bands. This integration enables submarine platforms to establish secure, high-capacity communications over a sovereign infrastructure. The system is also equipped with features that enhance resilience against signal interference, cyberattacks, and adverse conditions in the space environment.
Strategic Capabilities
With this new terminal, Indra aims to address the growing demand for high bandwidth in challenging operational environments. The company continues to work on naval combat cloud and seabed protection technologies. At the same time, the TSUB-40Ka strengthens Indra’s position as a supplier of next-generation naval capabilities. Indra systems, used by leading navies around the world, continue to be developed to enhance multi-domain operational capabilities.
