Connecting the world through secure and intelligent space infrastructure
In a hyperconnected world, telecommunications satellites are critical to ensuring real-time communications, global data coverage, and mission-critical links. At Sener, we design and deliver high-reliability systems for satellite communications, providing essential technology for secure military networks, commercial telecom constellations, and institutional programs. Our expertise ranges from passive RF components to active antenna arrays, ensuring coverage, redundancy and resilience in every mission.
We offer a comprehensive portfolio of telecommunications satellites components, including active and passive RF equipment, antennas, waveguides, and amplifiers. These subsystems are designed for optimal performance across the entire frequency spectrum, including X, Ka, S and UHF bands. Our systems support both fixed and steerable architectures, enabling high-throughput satellite services with dynamic coverage needs.
With over 30 years of experience in space communications, we are trusted by top-tier institutions and private operators to deliver robust, certifiable hardware for demanding orbital environments. Our involvement in leading programs such as SpainSat NG, XTAR and Solar Orbiter demonstrates our ability to meet the highest technical and security requirements.
We develop and manufacture the full chain of RF components in-house — from monolithic integrated circuits (MMICs) and amplifiers to transmit/receive modules (TRMs) and active pointing mechanisms. This vertical integration gives us full control over quality and performance, and ensures seamless integration with customer systems. Our active antennas have been deployed on both institutional and commercial platforms.
We approach each telecommunications mission with a full-lifecycle mindset. From design and prototyping to integration, qualification, and long-term support, we work closely with our partners to ensure mission success. Our flexible engineering model allows for tailored solutions across LEO, MEO, and GEO constellations.
In the SpainSat NG-I program, we designed and manufactured the active transmission and reception antennas in X-band, as well as the Ka-band mechanical reflector assemblies. Our involvement extended to S-band antennas, UHF systems, and OMUX filters, enabling robust multi-band communications with jamming resistance and high payload flexibility
We provide comprehensive telecommunications satellite solutions, including active antennas, RF equipment, tactical data links, precision deployment mechanisms and power electronics. Our systems ensure high-performance connectivity, reliability and redundancy across mobile, fixed and command applications in both space and aerial communication architectures.
We develop communications systems for space applications, including antennas, RF equipment and TTC units. Our technology supports secure links for satellites, deep-space and defence missions. With decades of experience and a flawless in-orbit track record, we deliver trusted subsystems for institutional, scientific and commercial communication programmes worldwide.
