Interoperable, ultra-low profile, high-gain satcom on the move


How we got here

In the beginning was an ASIC – the application-specific integrated circuit at the heart of our re-engineered electronically-steered phased array – the world’s first solid-state, enterprise-grade antenna for satellite communications on the move.

It was inspired by a discussion between a group of British engineering entrepreneurs about the feasibility of satellite communications connectivity on trains. Unsurprisingly, mechanically-steered parabolic dishes weren’t up to the task.

The essential requirements were, of course, an antenna profile low enough to slide under bridges and tunnels; the agility needed to track a satellite accurately from a moving platform; and the power to connect to the furthest geostationary (GEO) satellite.

This clearly indicated a novel digital solution using an active electronically- steered antenna (AESA). Its miniaturised design would have to be very different from its predominantly military predecessors which struggled to scale up at high frequencies – weighed down as they were by multiple circuit boards, cards and components – and whose economics were impossible in commercial applications.

The problem of the inevitable heat dissipation arising from dense electronics led to today’s highly inventive technology approach: analogue beamforming at baseband, doing away entirely with the need for power-hungry digital-to-analogue converters.

Many innovative features followed. Patents registering essential intellectual property have been filed internationally and include our closed-loop tracking process; beam alignment to any satellite transmitting a unique code (especially important for low-Earth-orbiting constellations); and a distributed array concept. Further patents are pending and more are planned.

However, it is our approach to analogue baseband beam forming – digitally controlled – that remains the foundation of today’s very low profile, high-gain array for communications on the move (COTM). This is the key to interoperability with any orbit and the failsafe performance required by demanding enterprise customers.

It became clear, early on, that building a business on a revolutionary ASIC alone would be like marketing petrol before cars were invented. It needed to be integrated into a fully-fledged antenna – designed for digital.

While founded in 2005, Phasor Solutions started out in earnest at London’s Royal Institution in 2010, an appropriate backdrop for the new company’s ingenious approach to developing its antenna’s form and efficacy. Successive funding rounds and support from multiple industry partners enabled it to develop and demonstrate its technology until it went into administration in March 2020 as the impending pandemic dented investor confidence.

Three months later, in June 2020, South Korean technology specialist Hanwha Systems formed Hanwha Phasor to acquire Phasor Solutions’ patented technology and related assets.

Hanwha Systems is a division of the leading Korean group, Hanwha, whose USD $57 billion revenue comes from aerospace and defence, advanced green energy and other innovative technologies. Hanwha Systems recently announced it will invest $300 million in OneWeb, the low-Earth-orbit (LEO) satellite communications company, furthering its space business ambitions.

Hanwha systems is boosting the growth of the new Hanwha Phasor antenna business, recruiting the best to build on its existing team, investing in new equipment and facilities and strengthening processes, systems and disciplines.

It is no longer starting out but scaling up. As Hanwha Phasor, it has opened an ASIC design centre in Cambridge, UK to spearhead its core technology; enlarged and enhanced its advanced central London laboratory and near-field test and integration facilities; and extended the capability of its far-field range and ground station at the historic research site in Chelmsford, Essex, UK (where radar was pioneered during World War II); and continues to expand its workforce across all engineering disciplines, operations and supply chain, programme management and support functions.

Hanwha Phasor’s full development lifecycle test capability is unmatched in the solid-state flat panel antenna sector and equips the business to enter the market with arrays of dependable high quality.

Following its technology concept demonstrations, Hanwha Phasor is now testing the sector’s first pre-production system prototype. This encompasses beam forming and steering, RF performance, modem integration, electro-mechanical performance and software interface and control.

The next step for our fully customised test platform is productisation and volume manufacture. Hanwha Phasor is investing substantially in an industrial engineering and strategic supply chain team to enable production to be ramped up across all its technology components. A partnership with Tier 1 global contract electronic manufacturer Plexus has been secured while the business has been working with the world’s best integrated circuit foundries for some time.

Hanwha Phasor, the original disruptor in ultra-low profile, high-gain satellite comms-on-the move connectivity, is firmly on track. It is ready to partner with systems integrators and service providers who will benefit from a well-resourced product roadmap – and the deep reserves of experience needed to deliver it.
