Ultra Electronics Avalon Systems case study


Ultra Electronics Avalon Systems is a specialist business within the Ultra Electronics group and is a leading provider of niche technologies and capabilities to the Australian Defence community across a number of domains, including Electronic Warfare, ISR, Tactical Communications, Maritime and Underwater Warfare.

Established in 1995, Avalon Systems quickly became a successful member of the Australia’s Defence industry through the delivery of sophisticated, indigenous EW systems and specialist signal processing software.In 2009 Ultra Electronics acquired Avalon Systems as a base for building its Australian capability aligned with the awarding of the Air Warfare Destroyer (AWD) Sonar contract.

Avalon Systems joined the Ultra group of companies in 2009 and now also provides indigenous support to Ultra Electronics Sonar Systems on the Air Warfare Destroyer Sonar contract. Ultra Electronics is a group of specialist businesses designing, manufacturing and supporting electromechanical systems, sub-systems, products and components for defence, security, aerospace and transport applications worldwide.

Vision4ce received an enquiry at the beginning of 2016 from Ultra Electronics Avalon Systems that led to a contract in March 2017 to provide a target tracking solution for unique application; the measurement of electro-optic and radar cross sectional signatures from an airborne platform. The hardware was then delivered to the customer May 2018 and initial flight trials took place September 2018. The whole project came to fruition over a period of nineteen months.

The bespoke application required two identical systems, one for electro-optic measures and one for radar measurements, which could be installed and deployed from a leased commercial helicopter. The ultimate hardware solution comprised the Vision4ce GRIP System with custom VMS tracking software, a dual axis servo platform, visual and infra-red tracking sensors, and a laser rangefinder.

Tracking mountThe Zeta dual axis, heavy duty, stabilised servo positioning pedestal, provided the ideal platform to mount the tracking sensors whilst delivering highly accurate and stable target tracking for either the customer’s electro optic cameras or radar system antenna depending on application.
