Indra Develops Ka-Band Satellite Terminal for Submarines

Spanish defense technology firm, Indra Sistemas, has completed the development and certification of a new Ka-band submarine satellite communication terminal. This technological advancement is designed to deliver higher transmission speeds, enhancing the operational capabilities of submarine platforms. The TSUB-40Ka terminal represents a significant step in modernizing submarine communications, providing faster and more secure connectivity. The implementation of this technology is crucial for military and governmental operations that require reliable communications in challenging environments.

The terminal operates in the Ka-band of the microwave spectrum, enabling broadband services with data rates exceeding several Mbps. Unlike traditional X-band (military) and Ku-band (civilian) systems, the Ka-band offers significant advantages in terms of capacity and efficiency. The shorter wavelengths associated with higher frequencies allow for proportionally smaller antennas, making the system well-suited for space-constrained platforms, such as submarines.

The utilization of the Ka-band allows for greater data transmission capacity, which is essential for modern submarine operations. This technology facilitates the transmission of critical information more quickly and efficiently, improving decision-making and real-time coordination. The implementation of the TSUB-40Ka terminal is a testament to Indra's commitment to innovation and excellence in the field of defense technology.

The terminal has been certified by HISDESAT to operate with the SpainSat NG satellite, ensuring secure, high-capacity connectivity based on sovereign infrastructure. The satellite operates across X-band, military Ka-band, and UHF frequencies, supporting secure, long-range communications for tactical operations.

The adoption of Ka-band terminals offers a significant operational advantage by combining military standards compliance (MIL-STD/STANAG) with enhanced connectivity capabilities. This ensures that communications are secure and reliable in critical operating environments. The ability to operate with the SpainSat NG satellite guarantees secure and high-capacity connectivity, crucial for military operations.

The company stated: “The TSUB‑40Ka terminal enables submarine platforms to take advantage of the advanced capabilities of the new Ka‑band satellite systems, such as SpainSat NG, expanding secure connectivity options for governmental and military operations.” These capabilities help enhance communications resilience against interference, cyberattacks, and adverse conditions in the space environment.

Indra's new satellite terminal offers several key advantages. These include higher transmission speeds, which allow for faster data transfer and improved responsiveness. It also offers increased resistance to interference and cyberattacks, ensuring the security of communications. In addition, the terminal is compatible with the SpainSat NG satellite, providing secure and high-capacity connectivity. The combination of these features makes the TSUB-40Ka an ideal solution for modern submarine communications.

The TSUB-40Ka terminal is an example of how cutting-edge technology can enhance military and governmental capabilities. By providing faster, more secure, and reliable connectivity, Indra is helping armed forces operate more effectively in challenging environments.

The SpainSat NG satellite plays a crucial role in the operation of the TSUB-40Ka terminal. By operating in the Ka-band, the satellite provides the necessary infrastructure for high-speed data transmission. This is essential for military operations that require secure and reliable real-time communication. The satellite also offers extensive coverage, allowing communication with submarines in various geographic locations.

The collaboration between Indra and HISDESAT, which operates the SpainSat NG, is an example of how companies can work together to develop advanced technological solutions. This collaboration is critical to ensuring that the Spanish armed forces have access to the latest communication technologies.
