// • Arralis wins UK Ministry of Defence (MoD) contract
• Contracted to design a scalable Multi-frequency Global Navigation Satellite System (GNSS) antenna

The MoD and Innovate UK, the UK’s innovation agency, has awarded a development contract to Arralis, a technology company servicing the aerospace and defence sector with a Design Centre in Belfast, Northern Ireland.

Arralis designs and manufactures high frequency semiconductor chips, modules and antennas up to and beyond 110GHz. Under the first phase of the contract Arralis will deliver a proof-of-concept study which de-risks GNSS Multi frequency or Wideband Antenna technologies, and advise the future system performance specifications before moving on to build a working prototype. Should the highly innovative development be a success an opportunity exists to expand the program into a major supply contract for the MoD.

Arralis were successful in their bid thanks to an innovative concept; designing a GNSS Antenna using a Meandered Spirial and High Impedance Surface. The current challenge is to develop solutions that can take advantage of opportunities presented by the emergence of GNSS signals for both military and civil applications. This will require assured precise Position, Velocity and Time (PVT) information for a variety of low Space, Weight and Power (SWaP) applications including navigation, targeting, guidance, situational awareness and time synchronisation.

For the MoD it is considered that the dismounted soldier applications represent the highest priority and most challenging conditions due to their exacting SWaP requirements and the necessary resilience required by military users. However, these antenna designs have applications far beyond the military; law enforcement, civil aerospace, mobile telecommunications, logistics, emergency management and infrastructure applications all could derive benefits from low SWaP antennae array systems for GNSS.
