For some time now, plastic pollution has been at the forefront of the environmental news agenda, but it’s only in the last few years where governments, corporations and the everyday consumer have come together to ramp up their efforts and face this problem head on. Most recently, restaurant chains and supermarkets have confirmed their commitment to reducing the level of plastic in their products, while governments have urged people to recyc...

Microsemi has announced completion of certification of its portfolio of cesium clocks to be compliant with the new G.811.1 recommendation (known as enhanced Primary Reference Clocks, or ePRC) from the International Telecommunication Union (ITU) for timing characteristics of enhanced primary reference clocks. This new standard raises the bar for frequency accuracy by an order of magnitude from 1x10E-11 to 1x10E-12.

In a world-first, an ESA-led team has built and fired an electric thruster to ingest scarce air molecules from the top of the atmosphere for propellant, opening the way to satellites flying in very low orbits for years on end.ESA’s GOCE gravity-mapper flew as low as 250 km for more than five years thanks to an electric thruster that continuously compensated for air drag. However, its working life was limited by the 40 kg of xenon it carried...

Assisting safer autonomous driving, STMicroelectronics has introduced what the company claims to be world’s first multi-frequency satellite-navigation receiver chipset suitable for safety-critical automotive applications and high accuracy positioning at the decimeter and centimeter-level for PPP and RTK applications.

High precision gearing and actuation company, Harmonic Drive UK has launched a series of offerings designed to meet the specific challenges faced in a range of extreme sectors on the frontiers of human endeavour. Called 'Special Environment' projects, these will include gearing and actuation products for sectors such as space, aerospace, military and defence, as well as offshore and subsea environments.

Global provider of wireless and positioning modules and chips, u‑blox, has announced the u-blox F9 technology platform, delivering high precision positioning solutions for mass market industrial and automotive applications. The platform combines multi-band Global Navigation Satellite System (GNSS) technology with dead reckoning, high precision algorithms, and compatibility with a variety of GNSS correction data services to achieve precision dow...

Researchers at the Universidad Carlos III de Madrid (UC3M) and the Universidad Politécnica de Madrid have designed and patented a new propellantless system for satellites that allows generation of electric power and on-board thrust. This innovation, which has led to two national patents, has attracted the interest of the European Space Agency and of the space industry.

(‘Tesacom’). Together, these companies further expand the footprint for Iridium Certus land-mobile services.

HUBER+SUHNER will display its connectivity solutions at SATELLITE 2018 - taking place next week, 13th to 15th March in Washington D.C.HUBER+SUHNER’s presence at SATELLITE comes following a successful win in the aerospace sector, after the company was recently awarded a sole connectivity contract to support the manufacture and test of a high-profile space program with over 900 satellites.

In a series of experiments, Cambridge researchers experienced weightlessness testing graphene’s application in space.Working as part of a collaboration between the Graphene Flagship and the European Space Agency, researchers from the Cambridge Graphene Centre tested graphene in microgravity conditions for the first time while aboard a parabolic flight – often referred to as the ‘vomit comet’. The experiments they conducted...
