Data Relay Satellite Market Report 2026

The data relay satellite market size has grown rapidly in recent years. It will grow from $9.67 billion in 2025 to $10.69 billion in 2026 at a compound annual growth rate (CAGR) of 10.5%. The growth in the historic period can be attributed to expansion of earth observation missions, increased reliance on leo satellite constellations, growth of space-based data services, investments in government space programs, advancement of satellite communication technologies.

The data relay satellite market size is expected to see rapid growth in the next few years. It will grow to $15.74 billion in 2030 at a compound annual growth rate (CAGR) of 10.2%. The growth in the forecast period can be attributed to increasing demand for real-time space data transmission, expansion of commercial satellite operations, rising defense and security applications, growing deployment of multi-orbit satellite networks, innovation in laser communication technologies. Major trends in the forecast period include increasing deployment of high-capacity data relay satellites, rising demand for continuous satellite communication links, growing integration of optical and rf payloads, expansion of inter-satellite link networks, enhanced focus on low-latency data transmission.

The growing frequency of satellite launches is anticipated to accelerate the expansion of the data relay satellite market in the coming years. Satellite launches involve placing artificial satellites into space using launch vehicles to achieve designated orbits for applications such as communications, Earth observation, navigation, scientific exploration, and defense operations. The rise in satellite launches is driven by increasing demand for global connectivity, as organizations deploy large satellite constellations to deliver high-speed internet services to remote and underserved areas. Data relay satellites play a crucial role in supporting satellite launches by enabling uninterrupted, real-time telemetry, tracking, and command communication during critical early orbit stages, thereby reducing reliance on ground station coverage and minimizing communication gaps. For example, in January 2024, Space Foundation, a U.S.-based nonprofit organization that supports space-related activities, reported that more than 2,800 satellites were deployed into orbit in 2023, representing a 23% increase compared with 2022. Consequently, the rising number of satellite launches is contributing significantly to the growth of the data relay satellite market.

Companies in the data relay satellite market are advancing technology such as inter-satellite links to facilitate seamless space-based communication. Inter-satellite links allow satellites to communicate directly with each other in space without the need to relay data through ground stations. For instance, in April 2025, Axiom Space, a U.S.-based commercial space infrastructure company, announced plans to launch two Orbital Data Center (ODC) nodes aboard upcoming Kepler Communications satellites. This initiative aims to enhance space-based cloud computing services by leveraging Axiom’s expertise in commercial space stations to enable real-time processing, cybersecurity, and AI/ML capabilities directly in low Earth orbit. The ODC nodes will be interoperable with Kepler’s optical data relay network and will comply with standards set by the Space Development Agency.

In May 2023, Viasat Inc., a U.S.-based satellite technology company, completed the acquisition of Inmarsat for $7.3 billion. Through this acquisition, Viasat intends to strengthen its satellite communications network by integrating Inmarsat’s GEO satellite fleet and aviation expertise with its own broadband technologies, thereby improving scale and service capabilities. Inmarsat is a UK-based provider of data relay satellite services.

Major companies operating in the data relay satellite market are Boeing Satellite Systems, Lockheed Martin, Airbus SE, Northrop Grumman, Thales Group, L3Harris Technologies Inc., EchoStar, SpaceX, Viasat, Intelsat, Iridium Communications, Telesat, ST Engineering iDirect, Globalstar, Axiom Space, Kepler Communications, Raytheon Technologies Corp., Hughes Communication, Warpspace, OHB SE, SSL, OneWeb.
