ROMSEY, England, February 6, 2013 /PRNewswire/ --

Roke Manor Research Ltd (Roke), a Chemring Group company, has achieved an
Ingress Protection (IP) certification for its Miniature Radar Altimeters
(MRA). This will deliver UAV operators greater flexibility in mission types,
including recovery from water, and reduced operating costs.

Both the MRA Type 1 and MRA Type 2 models have achieved IP67 certification,
following tests for their water and dust-proof resistance. This certification
means that Roke's MRAs meet the requirements for complete protection from dust
ingress and are waterproof up to a depth of one metre.

Used for a variety of UAV missions, from height monitoring to aerial
surveying, Roke's MRAs now give assurance to manufacturers and end-users of a
robust design which will not be adversely affected by environmental
conditions. It also enables drones to be recovered from the water without
risking damage to the sensitive altimeter sensor, and therefore saving costs
over the lifetime of the drone's operation.

Paul Webb, Unmanned Systems Business Sector Manager at Roke, said: "UAV
manufacturers purchasing our IP certified MRAs can be confident of reduced
lifetime costs as they don't have to be replaced if a mission results in the
UAV being ditched in the sea for recovery. With cost savings a key focus for
defence organisations, the assurance that altimeters, costing anything upwards
of £10,000 each, will remain operational is a vital consideration."
