A prototype 3D-printed antenna being put to work in ESA's Compact Antenna Test Facility, a shielded chamber for antenna and radio-frequency testing. "This is the Agency's first 3D-printed dual-reflector antenna," explains engineer Maarten van der Vorst, who designed it. "Incorporating a corrugated feedhorn and two reflectors, it has been printed all-in-one in a polymer, then plated with copper to meet its radio-frequency (RF) performance requirem...

A tracking system called HYPERION based on eye-safe lasers could enable aircraft, UAVs and even orbiting satellites to transmit vital data to ground stations more securely, quickly and efficiently. The development of HYPERION has been pioneered by a joint team through Innovate UK's HITEA programme: the University of Oxford with funding from the EPSRC, and Airbus Group Innovations with Innovate UK support.

Microsemi Corporation and STAR-Dundee have announced their collaboration to provide SpaceWire and SpaceFibre network technology using Microsemi's RTG4(TM) high-speed signal processing radiation-tolerant FPGAs. STAR-Dundee specialises in supporting users and developers of SpaceWire and SpaceFibre, which are data-handling networks for onboard satellites and spacecraft.

The University of Portsmouth is to host a centre of excellence for satellite data, which will promote economic growth in the UK’s space sector. The centre will allow the south coast business community to tap into satellite technology that could improve their products and services, for example, developing technology to help robot submarines use live satellite data to inform their route through the ocean – similar to drivers using live ...

Inner-city deliveries in Austria may soon be powered by pollution-free fuel cell technology that is also being explored by ESA for satellites and robotic missions to Mars. Austrian transport specialist HET Engineering has designed a quiet, zero-emission vehicle for sensitive traffic areas. With technical assistance from the DLR German Aerospace Center, the company's Citylog EMF vehicles will be small enough to navigate narrow and congested street...

The portfolio of radiation tolerant multiplexers from Intersil Corporation has been expanded with the release of two new, single supply 5V devices. The 16-channel ISL71830SEH and 32-channel ISL71831SEH multiplexers join Intersil’s 30V multiplexers, which have been onboard many satellite and space exploration missions, including NASA’s Orion spacecraft flight test.

Three teams of scientists are using glass in research projects that could bring graphene into the mainstream, allow windows to function as screens and produce ultra-slimline smartphone cameras. Scientists at the US Department of Energy's Brookhaven National Laboratory have developed a simple and powerful method for creating resilient, customised and high-performing graphene by layering it on top of common glass.

With data from satellites, there is generally a trade-off between resolution and the frequency of updates. This is the reason why most of the alerts already on Global Forest Watch, an interactive online forest monitoring and alert system designed to empower people everywhere with the information they need to better manage and conserve forest landscapes, are 500 or 250m resolution.

A NASA team has been tapped to build a new type of communications modem that will employ an emerging, and potentially revolutionary, technology that could transform everything from telecomms, medical imaging and advanced manufacturing to national defence. The space agency’s first-ever integrated-photonics modem will be tested aboard the ISS from 2020 as part of NASA’s multi-year Laser Communications Relay Demonstration (LCRD).

A flat optical lens just a billionth of a metre thick will let us see living creatures as small as a single bacterium better than ever before. The new lens, developed by researchers at Swinburne University of Technology, promises to revolutionise much of the technology around us.
