Leti, a research institute of CEA Tech, and Orolia, a specialist in accuracy and performance for terrestrial, aeronautic and naval transportation positioning, navigation & timing applications, have announced a sensor-data-fusion engine that ensures resilient positioning and navigation even in cases of global navigation satellite system (GNSS) jamming or spoofing.

Humanity is now more aware of its impact on the planet than ever before. The dangerous effects of climate change are well documented and, unless governments, businesses and society as a whole take drastic action in the near future, irreversible damage may be caused.

In a few months the European satellite system Galileo will be completed. Most devices with location tracking functions already support it. Even so, their manufacturers should endeavour to implement over-the-air access, as this is the only way that satellite selection can be adjusted on demand as needed – something which can be a critical factor.

A chorus of alarms serenaded the nervous astronauts as theEaglelunar module descended toward the moon’s surface. The tension was palpable, and the shrill ringing only added to their worries. Guest blog written byRanjan Sikand, Wind River Intern.

The University of Strathclyde’s Advanced Forming Research Centre (AFRC) is making its way into the space industry, working with Airbus Defence and Space (Airbus DS) and TWI to bring the manufacture of space propellant tanks back to the UK.

Skyworks Solutions has unveiled its latest high reliability solutions for demanding military and space applications with stringent operating requirements. Skyworks’ hermetically sealed, broadband low-noise and impedance-matched amplifiers function in harsh environments and can be leveraged in a multitude of communication platforms.

Whether for satellites in orbit or along the ocean floor, the demand for connections to enable the transmission of data, signals or electrical power increases every year. In aeronautics, the on-board equipment and materials of an aircraft must be able to withstand extreme climatic and mechanical conditions, because at an altitude of 10,000 metres, a small failure can have critical consequences. In this kind of application, failure is not an optio...

Design and analysis of superstrateintegrated differentially-fed circularly-polarised antennas are presented. The antenna consists of a metallic patch fabricated multilayer space-qualified printed circuit boards, integrated by a dielectric superstrate on top to establish suitable resonant condition for high-gain operation. The driven patch is excited by two orthogonal differential feeding pairs using sequential rotation technique for pattern symme...

On May 2019, the Graphene Flagship embarked on a campaign of zero-gravity parabolic flights to test novel thermal management graphene devices for space applications. The unique properties of graphene can significantly improve their performance.

Multi-national corporations and startups alike have begun to tackle the emerging sector of commercial spacecraft. Known as 'new space,' it is the sector where companies are introducing new designs that propel them to the forefront of technological advancement, in areas such as 5G networking and imaging.
