Hanwha Phasor: Redefining Satellite Connectivity with Next-Generation Flat-Panel Antennas
In an era where uninterrupted communication is a necessity across land, sea, and air, satellite technology is undergoing a major transformation. At the centre of this change is Hanwha Phasor, a London-based company that has built its reputation on delivering enterprise-grade, flat-panel antennas designed for mobile satellite communications.
This article explores the origins, growth, and technologies of Hanwha Phasor, including details about its headquarters in London, phone contact, founding background, and areas of expertise. It also sheds light on its contribution to the satellite communications industry and why the name “Hanwha Phasor” has become synonymous with innovation in phased array technology.
The Origins of Hanwha Phasor
Founded with a Bold Vision
Hanwha Phasor was officially founded in June 2020 when South Korea’s Hanwha Group, through its defence and technology arm Hanwha Systems, acquired the assets of Phasor Solutions. Phasor Solutions was a UK-based pioneer in electronically steered array antennas. By integrating this expertise into its portfolio, Hanwha Group laid the foundation for what would become one of the most ambitious satellite antenna projects in Europe.
Why London?
The decision to establish Hanwha Phasor London as its global headquarters was strategic. London not only offered access to Europe’s leading aerospace and telecommunications talent, but also connected the company to international markets. The headquarters is located at The Record Hall, 16 Baldwin’s Gardens, London EC1N 7RJ, United Kingdom. This prime location reflects the company’s global outlook and commitment to innovation at the heart of Europe’s technology hub.
Hanwha Phasor London Headquarters
Office and Facilities
The London headquarters of Hanwha Phasor symbolises the company’s vision of combining modern engineering with practical commercial solutions. The office, situated on the 4th floor of The Record Hall, provides not only administrative and design functions but also acts as the nerve centre for its research, development, and international operations.
Phone Contact
For direct communication, Hanwha Phasor could be reached through its official phone line: +44 20 3176 8700. This line served as the main corporate contact point for clients, partners, and collaborators across the globe.
Additional Facilities
While the London office was the flagship hub, Hanwha Phasor also maintained a specialist ASIC development facility in Cambridge, an area renowned for advanced semiconductor and communications research. Furthermore, to strengthen its global reach, the company established an office in the Washington D.C. area, United States, ensuring access to North American markets.
Specialties of Hanwha Phasor
Satellite Communications on the Move
Hanwha Phasor’s core mission was to design and deliver enterprise-grade antennas for mobile satellite connectivity. Unlike traditional parabolic dish antennas, which are bulky and less suited for dynamic environments, Hanwha Phasor’s technology was centred on flat-panel, electronically steered arrays. These provided high-speed connectivity without the limitations of mechanical movement.
Multi-Orbit Connectivity
A standout feature of Hanwha Phasor’s technology was its ability to offer seamless connectivity across multiple satellite orbits. This included geostationary (GEO) satellites for broad coverage and low Earth orbit (LEO) constellations such as OneWeb for low-latency, high-performance communications. The ability to “make-before-break” ensured connections were uninterrupted, even when switching between satellite systems.
Ultra-Low Profile Designs
The flat-panel antennas developed by Hanwha Phasor were ultra-thin and lightweight, making them ideal for installation on aircraft, ships, vehicles, and even smaller mobile platforms. This design philosophy prioritised efficiency, aesthetics, and practicality, all while maintaining robust performance.
RF ASICs and Advanced Phased Arrays
Hanwha Phasor also specialised in RF ASICs (application-specific integrated circuits) that powered their advanced phased array systems. These circuits allowed for electronically controlled beam steering, reducing latency and boosting connectivity even in challenging conditions.
Technological Innovations
The Land-Based L3300 Series
Hanwha Phasor introduced its L3300 and L3300B models, compact and resilient terminals tailored for land-based applications. These were particularly suited for military, first responders, and broadcast vehicles. With dual simultaneous receive channels and lightweight design, they demonstrated the company’s commitment to practical, high-performance solutions.
The Airborne A7700
Another milestone was the A7700 airborne terminal, designed to meet the stringent requirements of both commercial and military aviation. It offered scalable architecture, anti-jamming resilience, and full compatibility with LEO networks, positioning it as a revolutionary solution for in-flight connectivity.
Hanwha Phasor’s Growth and Workforce
A Global Team
By 2023, Hanwha Phasor had expanded to employ over 90 staff members worldwide. These employees were hand-picked from across the globe, forming a diverse team of engineers, scientists, and specialists.
Work Environment
The company prided itself on providing an inclusive work environment, competitive salaries, and opportunities for professional development. Generous relocation packages and sponsorships for highly skilled roles reflected its commitment to attracting top-tier talent.
Contributions to the Industry
Strengthening Mobile Connectivity
Hanwha Phasor’s vision was not limited to one sector. Its antennas were designed to serve multiple industries:
-
Aviation: Enabling seamless in-flight broadband.
-
Maritime: Supporting vessels with uninterrupted communications on the open sea.
-
Defence and Security: Equipping military vehicles and personnel with secure, reliable satellite links.
-
Emergency Services: Providing first responders with essential connectivity during crises.
Partnerships and Collaborations
The company engaged with several high-profile partners, including OneWeb for satellite compatibility and Lufthansa Technik for aircraft integration and certification. These collaborations underlined Hanwha Phasor’s credibility within the global aerospace and communications ecosystem.
Challenges and Shifts
Market Realities
Despite its technological promise, the satellite communications market is notoriously competitive and capital-intensive. By late 2024, reports indicated that Hanwha Phasor faced challenges related to revised market forecasts and strategic pivots by its parent companies.
Administration
In March 2025, Hanwha Phasor Ltd entered administration in the UK, highlighting the difficulties faced even by technologically advanced firms in balancing innovation with commercial sustainability. While some of its assets were later acquired by external companies, Hanwha Phasor’s innovations continue to inspire the next generation of satellite communications.
Legacy of Hanwha Phasor
Pioneering Flat-Panel Antennas
Hanwha Phasor will be remembered for its pioneering role in developing flat-panel, electronically steered antennas. These innovations proved that compact, ultra-low-profile systems could match or surpass the performance of traditional satellite solutions.
