80 attachment for counter-IED operations, the GCS-200 weighs around 10 tonnes, measures 5.5 m long and can clear explosive material from roads and spaces up to 2.6 m wide. It is powered by a four-stroke six-cylinder diesel engine with direct fuel injection, turbocharger and charge-air cooling. “While our GCS-100 concentrates on mobility with a lighter construction, the GCS-200 focuses on maximum survivability with a Hardox steel armoured protection,” Mikota added. “Other mine clearance machines have electronics and systems mounted on top of the vehicle, but on the GCS-200 everything is housed internally.” TE Connectivity showcased its new Series III ACT composite connectors, as a part of its Deutsch MIL-DTL-38999 series. “They are constructed using polyether ether ketone [PEEK], the highest performing composite matrix available with regards to robustness,” said Martin Cimini. “The Series III composite connectors – Class M and J – are up to 40% lighter than the 38999 III aluminium classes. The composite classes of M and J are also available with up to 1500 mating cycles for durability, compared with 500 mating cycles for the aluminium classes.” In addition to the composite shell, the circular connectors can be plated with olive-drab cadmium or electroless nickel (depending on conductivity requirements) and use gold-plated copper alloy contacts to protect against heat and oxidisation; they also have beryllium-copper EMI spring fingers for EMI protection. Insitu announced the integration of Logos Technologies’ Redkite wide-area motion imagery (WAMI) sensor into the Integrator UAV. Other versions of Logos’ WAMI technology have flown on aerostats, with data connected to a ground-based processor via a 10 Gbyte fibre-optic tether. “With the Redkite however it’s processed onboard the aircraft, with eight hours of storage – about 1 Tbyte per hour – which from 12,000 ft can detect and track multiple dispersed targets across a 12 sq km area, about 4 km in width,” said Alan Murdoch. “We’re using standard SSDs off the shelf, so we can scale with COTS technology.” Up to ten windows can stream the data at once, with snapshots and areas in the full field of view stamped with time and GPS coordinates or cross-cued with the electro-optical nose payload. The Redkite uses a greater than 50 MP camera and consumes 200 W (up to 300 W maximum). Payload weight is 11 kg, a reduction of 5 kg resulting from the current version’s use of a carbon fibre enclosure. Xenics Infrared Solutions displayed its short-wavelength infrared (SWIR) detectors for 2D imaging cameras and cores. The detector arrays are made using Indium Gallium Arsenide, which offers a very high quantum efficiency and April/May 2017 | Unmanned Systems Technology The GCS-200 fitted with the manipulator arm option, for removing heavy IEDs Insitu’s Integrator UAV fitted with Logos Technologies’ Redkite WAMI sensor
